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!
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!
Happy birthday to the world’s most awesome cousin!
Wait, I meant to say happy birthday from the world’s most awesome cousin! You’re lucky to have someone as wonderful and as cool as me in your life, cuz!
