Invisible People

This is the first draft of a poem I wrote for a book I'm writing, a compilation of short stories and poems. I don't usually write poetry, so it needs some tweaking, but here goes.

i see invisible people every day.
no, that's not quite true.
we all see them.
but you don't notice; i do.
but really, they aren't hard to spot.
there may as well be a neon sign
over their heads.
look in the lunch line.
i see three.
glasses boy, next to you.
the girl in boy's clothes.
nose-in-book girl too.
they're everywhere. don't you see?
i was one, a while ago.
i succeeded in being invisible.
don't answer in class, even if you know
the answer. never meet their eyes.
look at the floor when you walk.
no one will notice you're hurt.
oh, and hardly ever talk.
but it killed me somehow;
it built up inside me.
so i worked, and i broke through.
keeping people out is easy.
but this was hard. deep breath,
head up, shoulders straight.
go on, say "hi."
they won't bite you, goddamnit.
for heaven's sake, look them in the eye.
and now this is how you see me.
i smile at everyone i pass.
people smile back.
they sit next to me in class.
and now you all know my name.
i've found someone to be.
this life is so much better
when i can just be me.
but that girl. at the corner table.
please tell me that you see.
she's there all alone.
it's just killing me.
i stare, and i make my decision.
at the front of the group, i steer
my friends to her table.
"hey, mind if we sit here?"
