Your family welcomed me in with open arms and I’ll never forget that. I’ll work hard to make sure your sister has the life she deserves. Happy birthday brother-in-law and thanks again for welcoming me into your family.

Happy birthday to my brother from another mother. Hope it’s a great 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.

It’s your birthday, so feel free to party it up! And if my sister gives you flack for having fun on your birthday, just let me know.
