To the best brother-in-law, I wish the best of life. Happy birthday, man! May this day be filled with joy and love.

I know our family is a bit weird, but we are happy you are a part of it. Happy birthday brother-in-law!

It’s great to have such an amazing guy as family. I’m so glad you are my brother-in-law. Happy birthday!

I never know what to write in cards, I guess I’ll just wish you happy birthday and let you know that you are a wonderful brother-in-law.
