I want you to know that you mean so much to me and I cherish the friendship that we share with each other. Wishing a truly awesome birthday to my greatest friend.
Having you as my best friend is the best thing that has ever happened to me. You’re the best. Happy birthday.
There’s no greater friendship than the one I have with you. Wishing my best friend the best birthday ever.
Birthdays come around every year, but a friend like you only comes along once in a lifetime. I’m so glad that we’ve become best friends. Happy birthday.
You are much more than a friend to me, you are like the [brother/sister] that I never had. Happy birthday my [brother/sister].
Here’s to another year of celebrating our amazing friendship. I treasure all of the memories that we have together and look forward to new ones. Happy Birthday to my best friend in the world.
Wishing the happiest of birthdays to my best friend who keeps giving, even when [he/she] knows that I don’t have much to give in return.
We’ve been through the best of times and worst of times, and I’ll continue to stand by your side no matter what. Happy birthday to my best friend.
