I love my sister. She is simply amazing and I just couldn't imagine my life without her.
I know what you did, and I will tell Mom!
As far as sisters go, you're the best there is, but I'm still the favorite.
If you think I'm high maintenance, you should see my sister.
Little sisters - the only person in the world you can blame for the things you did and get away with it.
You're my sister and my best friend. If you think otherwise, just remember I know all your secrets.
If you trip and fall in life, I will be there to help you up - after I quit laughing.
When you have a sister, you never truly forget the past. If you do, she'll be happy to remind you of all your stupidest mistakes.
Our crazy family tree - we're just two nuts who survived it together. Love you, sis.
No matter how hard you try, sisters are the friends you can never get rid of.
Yeah, my sister scares me a little bit, but that's part of what I love about her.
Sisters may drive you crazy, get into your stuff and irritate you. However, if anyone else dares say so, a sister will defend you to the death.
A sister is a special type of angel on earth who brings out your best qualities.
Sisters help make the hard times easier and the easy times more fun.
Sister, we share so many moments that no one else will understand. We laugh at inside jokes, have our own catch phrases, and understand each other's joy and pain. I can't imagine anyone who would make a better best friend than you, and I'm so happy to have you in my life.
Being without your sister is like being without your heart and soul.
We start our sentences with "remember when" and end our days with a chat on the phone. As children, we fought and argued over everything, but as adults, we are the very best of friends. You are the one person I have always been able to count on and I love you more with each year that passes, my first and dearest friend.
Sister, no matter how old we get, being with you is like being a little girl again.
The best gift Mom and Dad ever gave me was you.
She's not just my best friend; she's my sister.
Sister, you are my human diary. You know all my secrets and the deepest wishes of my heart.
