As your elder sibling, it’s my duty to boss you around and act as though you’re always bothering me but seeing as today is your special day I’ll give you a break!
Happy birthday, sis! On your special day, I want you to know that no matter how old we get, the fact will always remain that you are my younger sister and I’ll always be there to look out for you.
You’re my little sis and I care about you and love you a lot! I hope you have a fabulous birthday today!
Having a younger sibling like me is tough competition and while you may not have won the title of favorite child when we were growing up, you’ll always hold the prestigious position of fav sister to me!
