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!
Happy birthday, sis! Although you can’t rewind and get any younger, at least we can stop counting from this year onwards to make sure you don’t get any older!
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!
We might have been each other’s biggest enemies at times as kids but as we’ve grown up, I’ve learnt to tolerate you much better! Happy birthday to you, sis!
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!
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!
