Happy birthday to someone who was always stuck being the Robin to my Batman. You will always be my favorite sidekick in life.

You have always helped me get out of trouble, and for that I am thankful. Although, most of the time you were also the person who got me into trouble. Thanks anyway cousin.

Your presence in my life is a source of wonder and happiness. I’m so glad to be even a small part of your life. Have a spectacular birthday cousin!

I am so lucky I have a cousin like you. You are someone I can always rely on, and I hope your birthday is filled with joy, love, and laughter.

I wish you health, happiness, and love this year for your birthday. If you don’t get them all this year then hopefully you at least get health. That way you can live long enough to achieve the others!

Growing up with a cousin like you has been the best type of adventure. I’ve loved every crazy, stupid, and exciting moment spent with you. I hope your birthday is delightful.

I have loved to disturb you, worry you, and more importantly annoy you. However, my favorite thing is to simply love you. Happy birthday to the world’s best cousin.

Happy birthday to my partner in crime. For every fun exploit you were always right beside me. Thanks for making life an adventure worth having.

You have so much potential in life and so much to offer the world. In all your successes don’t forget the people you have impacted and influenced along the way. People like me. Your favorite cousin.

I’m so glad that I have had a cousin like you to help guide and support me. I’m even more glad that now I’m finally taller than you!

The most valuable things in life can show up in the most unlikely places. Like cousins. You mean so much to me, and I adore you.

I’ve watched you grow over the years and I couldn’t be prouder of the young man you have become. Today I am wishing you many more birthdays filled with endless love and laughter.

Some wisdom for my favorite cousin: Don’t dwell on the dimness of the past, but instead press on for your future is incredibly bright.

When I was lonely you were a friend, and when I cried you cried with me. I will never forget all the ways you’ve been there for me and all the things you’ve done. Thanks for being present in my life.

Even though every day brings new challenges great or small. Remember that you have an inner warrior ready to conquer every battle. I hope your birthday heralds a year filled with greatness.

Getting older really makes you appreciate things more than when you were a child. I really do appreciate and treasure every moment spent with you.

Bickering with you over the years has become not only my favorite past time, but has taught me that there is more than one way to say I love you.

There are lots of parts of my childhood I would like to forget, but none of them include you. Thanks for being a fond memory I can always look back on with happiness.

You help make life worth living and dreams worth dreaming. Wishing you all the very best on your birthday cousin.
