Happy birthday to my younger sister who a lot of people think is actually my elder sister!
I’m sure it’s only because you’re so wise and mature that people think you’re older than me anyway, sis! Either that or I just seem super young and immature!
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!
Over the years you have driven me up the wall and tried my patience time and time again, but really I have you to thank for that as it’s partly down to you that I’m such a calm, patient, and zen person nowadays!
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!
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!
