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 know that it’s your birthday today, yet I can’t help but feel like it’s also sort of mine too seeing how I’m the lucky one to have a best friend like you!
I hope you have a totally fabulous birthday, girl!
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!
