I figure your birthday is a good time to remind you that even though you are my brother-in-law, I consider you a blood brother. I’ve always got your back if you need anything, just say the word. Oh, and happy birthday, I hope it’s a great one!

Happy birthday, dear brother-in-law! I really appreciate how you have always taken care of my sister and how you always have her best interests at heart. It makes me happy to see how much you care about each other.

A lot of times in-laws don’t get along. I’m sure glad we are the exception! Happy birthday bro, I hope you have a good one!

I’m not great at birthday wishes, but I just want to say you are a pretty amazing brother-in-law. I hope you have a great birthday.
