I can’t imagine my married life being as lively as it is without the presence of my loving sister-in-law.

Dear sister-in-law, you became my best friend even before I married into this family. On your birthday, I want to express my gratitude to you for accepting and embracing me with open arms.

When you married into this family, my dearest sister-in-law, all fun unlocked for me, and I hope to have a celebration as awesome as you are.

I am proud of my brother to have wooed an amazing woman like you. Because of him, I got the chance to enjoy my life with the loving sister that you are.

I understand why I never had a sister because God had planned for you to eventually become part of our lives.

The only thing that my brother did to make me proud is that he got a fantastic woman like you to say yes.

My family sure got lucky to have their son become capable of impressing a wonderful woman like you, my loving sister-in-law.

I am most grateful for the way fate intertwined our lives together, maybe not as sisters by blood but definitely as sisters beyond blood.

Dear sister-in-law, you are the one person who understands and listens to me the most. Even my blood-related family could not take your special place in my life.

Darling sister-in-law, I couldn’t be any happier than to celebrate the coming of another year I will spend with you.
