As my younger brother you might get to make fun of me for being older than you, but just remember that every year my cake will always be bigger than yours because it needs to hold more candles!
I’m wishing a very happy birthday to you today, bro!
I’ve spent so many years laughing at you and I’m sure that I’ll spend many more laughing with you! I’m so lucky to have a funny younger brother like you!
Happy birthday, little brother! You might be jealous of your big sister in many ways, but I’ll always be envious of the fact that you’ll always be younger than me!
