Happy birthday to the best brother in the whole entire world!
You are one of the few people I know I can always rely on and who will forever be there for me whenever and wherever. You’re my rock and very best friend.
From your ever-adoring sister, I’m wishing you only the very best today and always.
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!
