You are the best brother-in-law

Dear brother-in-law,
you have been a part of this
family for many years now.

I admire your love for my sister
and the affection you give to her.

You have shown so much respect
and love to my parents, as if they
were your own.

You are the best brother-in-law I
could have and you deserve to
have a fabulous birthday today.

Happy birthday, extended brother!
