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!
There might have been a time when we were younger that I would’ve traded you for something as small as a chocolate bar, but now I wouldn’t trade you for the world!
I’ve come to love and embrace the fact that you’re my annoying little sis and you always will be! I wouldn’t have you any other way!
Happy birthday from one wise elder sister to her younger and more beautiful baby sister!
I was trying to think of something funny or witty for your birthday message this year, but all I could think of was silly jokes and cliche anecdotes. I guess you got the gift of being both the younger one and the funny one, sis!
I was going to make a joke about how you’re getting older, but that immediately backfires as I’m always going to be older than you! At least we can make fun of each other as we grow old together!
It must be so nice not ever having to worry about your age because at least you’ll always be younger than me! That’s possibly the best gift I could ever give to you!
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!
