My friend's brother is almost seventeen And can't be trusted with his own set of house keys Because he keeps losing them Went out with friends wakes his mom up Knocking on the door at 3AM, he says I need a key, believe in me, I'm mature now I'll lock the door, if you can trust me more I might get locked out He stole his mom's set out of her jacket Biked it into town to get a key cut, but he lost them Grounded for 3 months He's got some growing up to do, if you ask me Dad wants to kick him out ASAP, he disagrees I need a key, believe in me, I'm mature now I need a key, believe in me, I'm mature now I'll lock the door, if you can trust me more I might get locked out
