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 want you to know that I look up to you as if you were my elder sister, cousin. It has nothing to do with age, only the fact that you look so much older than me!
You might want to forget about your birthday but I never could! I’ll take any opportunity to remind you that you’re getting older, my friend! Happy birthday!
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!
