You’re another year older and more beautiful than ever, little sister! Happy birthday to you!
Just a word of wisdom from your dear elder sister, keep hold of your beauty and cherish it for as long as you can because once you get to my age those good looks won’t stay around for long!
You might be growing up in age, but we’re yet to see you grow up in maturity! You still have plenty of time for that though, little sis! Happy birthday!
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!
