Like lots of little brothers you were naughty, mischievous, cheeky, and sometimes annoying growing up, and I’m so glad to see that nothing has changed since then!
Sure, there were times growing up together when I might have wished that you were adopted or my brother from another mother but in the end, I’m glad you’re my blood-brother!
I could definitely have done a lot worse and really there’s nobody else I’d rather have grown up with, bro!
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!
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!
