He will never know

It was monday, first day of school of the week.
We were studing with some... "people" -that I can't call friends-
and a guy came to me and asked me for a book beside me,
when I took it and gave it to him
he saw it, he saw my wrist, my scars.
I didn't realize he did, since he asked me: "Why do you cuts?"
I thought he won't say anything  -that was what I wanted- but he wasn't really worried or anything like that. He, actually, almost scream that at me, when i was hoping that if he asked he would be a little more discreet.
I really didn't want to answer him, i didn't have to.

And two seconds later, I realize why he asked... He never felt like me.
Of course not. He's cool, funny, popular, he date and hook up with any girl he want to, everybody likes him, he have friends everywhere, everybody want to be his friend.

So I've smile to my inside, and told him "You'll never understand, mister popularity".
