Congratulations! You've married one of the most special people on this planet: my best friend. We've been waiting for this moment as long as I can remember - planning our wedding days and picturing our sophisticated adult lives. Now that the time has finally come, there are a few things I want to say...
First off, thank you. Thank you for taking care of our girl (yes, she's mine too). Thank you for making her so incredibly happy. Thank you for treating her like the princess that she is.
I've known her since we were just kids and I've been with her through the ups & downs on her way to finding you. I always knew you were out there, Mr. Right; trying to find your girl who fits into the glass slipper (Cinderella reference aka important things you're going to have to learn).
Don't worry, I'll show you the ropes. Not to brag, but I'm kind of an expert on her by now. If you ever want to surprise her or pick out the perfect birthday gift, just call me. I'll teach you what to do when you've messed up and what to do to fix it (this usually involves food).
Now your wife and I are kind of a package deal, so lucky for you, you're married to me too. Expect daily phone calls and weekly visits. Oh, and the fact that I will be living right next door (this has been prearranged for a while now). She's been my "hubby" since we were in high school so you're going to learn to love me (almost) as much as you love her.
I know I don't have to tell you this, but you've married a really amazing woman. She's strong, beautiful, kind, and has the biggest heart around. I know you will treasure her like the diamond that she is.
Thanks for letting me be a part of your happily ever after. I can't wait to meet you.
Sincerely,
Your Future Best Friend In-Law
