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!
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!
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!
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!
