You were always super welcoming to me even before I became your brother-in-law. I really appreciate that. Happy birthday and thanks for making me feel like part of the family.

I never had a brother, but with such a great brother-in-law, who needs a biological brother! Hope your birthday is as awesome as you are.

When you and my sister were dating I always hoped you would become my brother-in-law. And now you are! Welcome to the family brother, I hope you have a really good birthday.

I’m really happy that we were able to become friends. I know in-law relationships can be a bit rocky. So here’s to new brothers! Happy birthday.
