You might finally be growing up and catching me up, little bro, but you’ll still always be younger than me! In my eyes, you’ll forever be my baby brother!
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!
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!
