Cousin by blood, best friend by every summer we spent together. Happy birthday to someone who's always felt like home.

You were my first sleepover, my first partner in crime and my first real friend. I'm so glad we never grew out of each other. Happy birthday, cousin.

Our parents put us in the same backyard and we did the rest. Thanks for being the closest thing I have to a sibling. Have an amazing birthday.

Life got busy, we moved, we grew up, but every time I see you it takes about thirty seconds to feel twelve again. Happy birthday to my favorite cousin.

Not everyone gets a cousin who also turns out to be one of their favorite people. I did. Hope your birthday is as great as you are.

You've grown into someone our grandparents would be so proud of. I hope you feel that today. Happy birthday, cousin.

Thanks for always being the one who reaches out first, who remembers the little stuff and who keeps this big family connected. Today, the family celebrates you.

Whenever family life got complicated, you were the one I could roll my eyes with across the room. That kind of understanding is priceless. Happy birthday.

Cousins are friends you don't have to explain the family to. You've been that and more. Have the best birthday.

I'm proud of everything you've built this year, and even prouder to call you family. Happy birthday, cuz.

You're the cousin everyone hopes will be at the reunion, and the one who makes it worth the drive. Happy birthday.

I still remember you defending me against the older kids at Grandpa's lake house. You've been in my corner ever since. Happy birthday, cousin.

Happy birthday to the cousin who taught me how to catch fireflies, sneak cookies from Grandma's tin and stay up past midnight without getting caught. Mostly.

Every Fourth of July, every Thanksgiving, every summer at the lake has you in it. Here's to making a lot more memories, cousin. Happy birthday.

Remember the 'secret club' we started in the treehouse? I still know the password. Happy birthday to its only other member.

Kids' table veterans for life. Happy birthday, cousin. Someday they'll let us sit with the grown-ups. Maybe.

Thanks to you, I know every word to every song on Aunt Linda's road trip CDs. Not sure if I should thank you or blame you. Happy birthday.

The holidays were always better because you were there. Even now, I check the guest list to see if you're coming. Happy birthday, cuz.

We shared bunk beds at Grandma's, a lot of bad haircuts and one very questionable attempt at running a lemonade stand. Happy birthday to my business partner.

Some of my happiest memories are just you and me in a sleeping bag on Grandma's living room floor, giggling until someone yelled. I hope today is just as happy.

Every family photo from the nineties has the two of us in matching outfits our moms picked out. I forgive them. Happy birthday, cousin.

Happy birthday to my favorite cousin. Don't tell the others, there's a lot of us and I'm outnumbered.

We're related, so technically I have to love you. Lucky for you, I'd do it anyway. Happy birthday.

Cousins: like siblings, but without the fights over the bathroom. Happy birthday, cuz.

Happy birthday to the only cousin who actually laughs at Uncle Gary's jokes. Your patience is truly inspiring.

You're my favorite cousin, and I'm putting it in writing so you can use it as evidence at the next reunion.

Another year older, and you're still the one the whole family blames for the broken window in 2004. Statute of limitations should kick in soon. Happy birthday.

I'd wish you happy birthday in person, but I'm saving my energy for the reunion gossip. Have a great day.

Happy birthday to the cousin who still owes me a rematch at cornhole. Name the time and place.

At family events we're the ones in the corner, judging the potato salad. I wouldn't want anyone else as my co-critic. Happy birthday.

Grandma always said we were trouble together. She was right, and I'm proud of it. Happy birthday, cousin.

Happy birthday, cousin! Have a great one.

Sending big birthday hugs your way, cuz.

Family by chance, friends by choice. Happy birthday.

Hope your day is full of cake and good people.

Cheers to my favorite cousin on your big day.

Thinking of you today. Let's catch up soon, cuz.

Another year, another reason to celebrate you.

Love you, cousin. Enjoy every minute today.

So glad we're family. Happy birthday!

Your birthday just gave me an excuse to text you. Call me later?

We used to live ten minutes apart, and now it's two time zones. Still my favorite cousin. Happy birthday from far away.

I hate that I only see you at weddings and funerals these days. Let's fix that this year. Happy birthday, cousin.

Even though we're miles apart, I still think of you every time I hear our song from summer camp. Hope your day is wonderful.

Sending birthday love across the country. Pretend I'm there stealing the frosting off your cake.

It's been too long since we sat on the porch and talked until the sun came up. Happy birthday. My guest room is always open.

Social media keeps me updated on your life, but it's not the same as a hug. Consider this one sent. Happy birthday, cousin.

Distance can't change the fact that you're one of my favorite people. Happy birthday. Let's plan a visit before next year's reunion.

God blessed our family with you, and I'm grateful every day. May this year bring you peace, health and joy.

Praying that your birthday is the start of a year full of blessings and good surprises, cousin.

May the Lord keep you and your family safe and happy this year. Happy birthday from all of us.

Thanking God today for every summer, every holiday and every prayer we shared growing up. Blessed birthday, cousin.

Sending you love, light and every good thing on your birthday. You deserve a peaceful, happy year.

From Grandma's porch to grown-up life, Through every joy and every strife, You've been my cousin and my friend. Happy birthday, start to end.

We stole the cookies, broke the chair, And blamed it on the family bear. The grown-ups knew and let it be. Happy birthday, cousin, love from me.

A cousin is a gift you get Before you even know, A friend who stays as years go by And watches as you grow.

Here's a wish from me to you, For skies that stay a sunny blue, For friends and fun and cake galore. Happy birthday, cousin, and many more.

Happy birthday to my cousin, who has somehow been both the most chaotic and the most dependable person in my life. When we were kids, you were the one who came up with every terrible idea, from the backyard zip line to the haunted house in Grandma's basement. As adults, you're the one who drove four hours when my car died and showed up with coffee and jumper cables. I'm so grateful we grew up together and that we've stayed close even as life pulled us in different directions. I hope this year is full of good surprises for you. Love you, cuz.

Dear cousin, our family has changed so much over the years. We've lost people we love, welcomed new babies, moved to new cities and argued about where to hold Thanksgiving more times than I can count. Through all of it, you've been a constant. You call when it matters, you show up when it counts, and you still make me laugh like we're kids at the kids' table. I hope you know how much you mean to me. Have a wonderful birthday, and let's make this the year we finally take that cousins' trip.

Happy birthday to the cousin who was basically my sibling growing up. Our moms swapped us back and forth so often that I'm still not sure whose house I lived in. I learned to swim in your pool, cried through my first breakup on your bed and ate more of your mom's mac and cheese than anyone should. You've been there for every big moment in my life. I can't wait to celebrate a lot more of yours. Enjoy today, and save me a seat at your table.
