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

Happy birthday to a lovely woman who is beautiful, intelligent and reminds me a lot of myself. I love you, sister!

Sending this message to wish my beautiful sister a Happy Birthday from across the coast.

Thank you for being my greatest inspiration and my best friend, Happy B’Day darling.

I am the luckiest person in the world because you are my sister.

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!

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.

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.
