Happy birthday to the best, finest, greatest, coolest, grooviest and bodacious sister ever born...anywhere in this whole wide world

Dear sis, you have taught me so much. There is no better teacher than you.

May you be overwhelmed with hugs and smiles on your special day. Wishing you a happy birthday.

Sister, you're the best friend a girl could ever have. I'm so glad you're mine. Have the happiest of birthdays.

You're the best sister anybody could wish for. I'm glad I have you for real.

Sister, you're everything to me. I'm so lucky to have you in my life!

You'll always be the loveliest sister in the world. Hope you have a fantastic birthday.

I may not speak to you every day but you're always in my heart and soul. Happy birthday, dearest sister.

It's great to have an amazing sister — and even more amazing friend — like you. Have a great birthday!

Sis, you have a bigger heart than anyone I know. It’s so big that you love me no matter what, despite my all-too-frequent not-so-nice side and few-and-far-between nice side. I love you for that.

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!

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!
