To the lucky groom-to-be,

I have been waiting for you, ever since the days of tying white bath towels around our torsos and pretending they were wedding dresses. I know you even more than you think because she has been dreaming of you and describing you to a t for as long as I can remember. She has been waiting for her perfect partner in crime, and for the time being, has settled for me. She has been nothing more than my best friend, and you are going to take my place.

My sister's future husband, be patient with her. I know first hand how she can be. It's no walk in the park. She is stubborn and headstrong and would rather rip her own teeth out than admit whats wrong with her or ask for help.That is how she is, but learn to bend with it. She is like a kiwi; its a pain to peel apart the shell and the seeds get everywhere, making you want to give up half way through, but the center is sweet and worth all the effort.

Be there for her. She is the type that bottles things in until one day she explodes on everything around her. Be there to listen to her and to fill her cracks. And if you did not make it in time, please pick up all the pieces. She is strong, but even she has her weak days. Support her, tell her everything will be ok, and even if she still does't believe it, then show her. That is what she needs more than anything.

I ask you, future-brother-in-law, please respect her. I know that seems like a no brainer, but she has been hurt before and hurt bad. Treat her as you would your sister and love her as your best friend. She is one of the most loyal and loving people I know, so do not take advantage of that. Give back to her everything she gives you — give her your heart since she has already given you her world. Cherish her, honor her, love her.

It is a hard job, I know, I have been doing it for my entire life. I have been by her side; through every smile, laugh, cry, and every dramatic fallout she's had with a boy leading up to you. So I can easily say, the hardest part is giving it up to you.

To my sister's future husband, please, do not let me down.
