You've always been my cousin but as the years go on you’ve become more like a bro to me, because just like a brother you love to irritate me! Happy birthday!
I bought you a birthday gift, But then really I thought I should get you another Since you’re so much more Than just a cousin, to me You’re also a brother!
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!
