speech for my sissy and new bro

First off I would like to thank Marc and my sister for letting me be a part of their big day,and for those of you who know my sister, you know I never really had a choice.
My entire life she has always been the quintessential big sister, bossing me around, telling me what to do, picking on me and all that...but fortunately she has always looked out for me too. Over the years we have been many different things to each other partners in crime, stylists, therapists, worst enemies and best friends. Sometimes I call her my second mom because she has truly influenced the woman I am today, and I try really hard to live my life in a way that my sister would be proud of. She has always been someone to lean on, blame things on, and learn from. I find myself thanking her in my dreams for making mistakes before i could so that I knew not to do them or simply how to get out of them. I could have never been the older sister. So thank you.
We know each other in a way that only sisters who have shared a small bedroom for 18 years can..in that room there was a lot of laughing, a lot of crying, secret sharing, planning and fighting, you name it, we went through it together. And when she became a teenager and I became just the little sister who could never understand her world but wanted so badly to be apart of it, I did what any good little sister would do, I read her diary and used it as blackmail.

I remember adults would always tell us, as we were bickering that ONE day we would be best friends, but our biggest secret was, that we already were. She is the only person who I can be so angry with one minute, and the next be laughing with all in the same breath. Although we still fight and hit each other with brushes I know that one thing will always remain the same she will always love and support me, whether she likes me this week or not. I think that is what will make her a great wife.
I could not have chosen a better man than Marc to share my best friend with. He is patient, understanding, kind, a former gaucho, and most importantly an excellent dresser. Marc is an amazing and rather brave man for committing his life to my sister. I am comfortable sharing her with you, but if I am sure of anything Marc I am sure of this, she will boss you around, clean at inappropriate times and always be late, but she will also always love you, support you, challenge you, comfort you and look out for you. Don't argue with her if she has a brush in her hand, don't steal her clothes, and don't ever be afraid that she will leave you because she spent years training you, and she doesn't take that lightly. Take care of each other and keep making each other better. Give your hearts to one another unconditionally because that is what true love really is..It is not this fairytale life that never knows pain, or sorrow but two souls facing it together and diminishing it with unconditional love. And to borrow some words from Shakespeare, Love is not love which alters when alteration finds, when life gets hard, when things change, true love remains the same. Everyone is here today to celebrate your love because they believe in you as a couple. So keep believing in each other, be kind to one another and lastly to a love that will not alter, Congrats and I love you both
