Lower Than Atlantis - Grounded

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
