So Grown Up

What happened to the boys we fucked with at school
Now you're in love with a man the same age as your dad
And i'm in love with a girl that i can't stand

What happened to the men we lost our virginity to
The older we get the younger we seemed
Two little girls with wet rosy cheeks

And you don't seem all that different now
You act like a woman but you look like a child
We're so grown up now

I forget which skin to slip into
I forget whose skin to get under
I don't know how to behave when i'm sober
Every time that i go home
I feel like a ghost that stole my own thunder

And you don't seem all that different now
You act like a woman but you look like a child
And i don't feel all that different now
I look like a woman but i act like a child
We're so grown up now

Don't forget about me, don't forget about me
Don't forget about being seventeen

If only i could shed my skin
Slither out and let it rot so i can't slip back in
Cos i don't know how to be myself
Will they want me when my innocence runs out
And we're so grown up now
Ending phone calls with look after yourself

Does he use those lips to kiss his wife and kids?
You're a good girl, so much better than this
