behind the bars/between the lines

I hide behind these bars
with a pen and a pad
and speak of these scars
from the times that I've had
I put on this mask
I'm invisible now
and this number, you ask
is divisible how?

Now, I know what you're thinking
and you're wrong to assume
that inside I'm just sinking
while I hide in my room
I just lie on my bed
and look up at the stars
my whole world's in my head
along with my scars

I'll just peer through these bars
and deep into the pad
soon I see all these scars
from the times good and bad
as I take off the mask
i'm convinced you won't see
or atleast that you won't ask
of the way things have been

you think I'll just keep drinking
and hide in my cell
yeah, I know what you're thinking
I built my own hell
built it up in my head
to keep me contained
so when you wind up dead
they won't think I'm to blame
