Lyrics:

Lines form on my face and hands
Lines form from the ups and downs
I'm in the middle without any plans
I'm a boy and I'm a man

I'm eighteen, and I don't know what I want
Eighteen, I just don't know what I want
Eighteen, I gotta get away
I've gotta get out of this place
I'll go runnin' in outer space, oh yeah

I've got a baby's brain and an old man's heart
Took eighteen years to get this far
Don't always know what I'm talkin' about
Feels like I'm livin' in the middle of doubt

'Cause I'm eighteen, I get confused every day
Eighteen, I just don't know what to say
Eighteen, I gotta get away

Woah, lines form on my face and my hands
Lines form on the left and right
I'm in the middle, the middle of life
I'm a boy and I'm a man
I'm eighteen and I like it
Yes, I like it
Oh, I like it, love it, like it, love it
Eighteen, eighteen, eighteen, eighteen and I like it
