It’s so wonderful to know that you’re not only my sister (and a great one at that) but also my best friend in good and bad times…when I really need you. I got your back, too. Have an incredible birthday!
Happy birthday to the best, finest, greatest, coolest, grooviest and bodacious sister ever born...anywhere in this whole wide world
Each and every day, I find so many reasons to be glad — no, ecstatic — you're my sister. I love everything about you.
Every day, I just pinch myself…because I'm so lucky to have the nicest, happiest, smartest, funniest and most supportive sister as my best friend.
Sis, I love you more than you can ever imagine. In fact, take how much you think I love you, double this amount and multiply by 1,000. On your birthday, multiply this amount by 1,000,000.
Despite our arguments and our differences, you are still the most important person in my life.
Sure, you can pick your friends but not your family. But, Sis, I would have picked you as my sister and my friend. You’re the best sister and friend anyone can ever have. I love you.
Okay, you've had to listen to me go on and on for what must seem like forever to you. But I have one more thing to say, and I don't care if you want to hear it or not. I love you. I'm so glad you came along for the ride we call life. Happy birthday to the most patient, loving sister anyone can ever have!
Happy birthday to a sister who has redefined what it means to be family! It means everything!
A better sister I could never find. Really. Happy birthday, sis!
Even though we argue with each other, yell at each other and irritate each other, I consider you my BFF through thick and thin. I love you, sis! You’re the greatest!
I don't think I could have made it through the teen years without you, sis! You've always been there for me, even when I didn't want you to be there. Happy birthday! I am here for you...now and forever!
When you came into our world, we became a family. The family portrait wasn't complete until you came along. I love you, sis! Happy birthday!
Sisters are supposed to be bossy, vain and that other word for witchy. But you’re none of those things. You’re just, well, amazing! Happy birthday, sis!
May your special day bring you all the joy and love you could handle...and then some. You deserve every wonderful moment.
Happy birthday, sis! Friends may enter and exit my life at will, but we're family, so that's forever.
Happy birthday to a sister who brings so much happiness and warmth into my life (yep, that's you, sis).
There's nobody I'd rather call "family" than you. You are remarkable in every way, especially as my sister. Happy birthday, sis! I love you.
I'm so glad that you're my sister, someone who redefines what family really means. Happy birthday, sis!
