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!
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!
On your birthday this year, little brother, I propose we make a pact. I won’t reveal your age, so long as you don’t tell anyone that I’m even older than you!
Happy birthday, little brother! If there’s one thing you should’ve discovered from having an elder sibling like me is that we only get more awesome each year!
Your birthday is the perfect opportunity for me to remind you that you’re getting older! Perhaps on one of these birthdays, you’ll start getting wiser too!
You’re not just a cousin but a brother too, but don’t be fooled into thinking that means you’ll get two birthday gifts this year! Happy birthday to you, bro!
