When people think you're still a kid...

My friend: I want to go on an adventure!
Me:Awesome!! Who do you wanna go with?
My friend: With a guy!
Me: Because you wanna climb trees and mountains?
My friend: Sam, youre still a kid.
And then I'm thinking "Are you kidding me buddy? I'm a month and 2 days older than you are! And you think I'm still a kid?!?! What the heck?!"
