Dear future brother-in-law,

I hope you understand how lucky you are. You’re lucky enough to love and be loved by the amazing and inspiring woman that I get to call my big sister. As we both know, she is so incredibly special, and I am so grateful that you have found each other.

I hope you know that you won’t be just marrying her; you’ll be marrying the whole family. We’re loud and crazy at times, but we love you both so much. We love how much brighter her smile is because of you and we can’t help but smile when we see her eyes light up every time she talks about you. We’re her home team, but we can’t wait to make you an official team member.

I also want to wish you good luck, in the most sincere and caring way possible. Growing up with my sister means I saw (and avoided) the crabby version of her when she hasn’t had her coffee, and the pushy version of her when she wants to get her way. We both know how stubborn she can be and how much she hates being wrong. Listen to what she has to say, but don’t be afraid to stand your ground...and make sure she has plenty of coffee before you do.

Thank you for being such a wonderful man. Thank you for being the gentleman she deserves, and the type of man my family has always hoped she’d end up with.Thank you for being yourself around our family and joking around with us like we’ve known you forever. Thank you for being patient, goofy, kind, caring and sweet towards my sister, and for making her the happiest she’s ever been. Please continue to make her happy, or you’ll be getting a lecture from me.

Thank you for all that you’ve done, and for everything I know you’ll do. I think you’ll be an amazing husband who both completes her and keeps her on her toes. I also think you’re going to be a pretty great bonus brother. She’s lucky to have you, but so are we.

Sincerely,

Your future sister-in-law
