Obsession is sometimes... scary.
Ever seen the movie Obsessed? Yeah, scary, right?
That's how the one you're being obsessed with would feel.
In the first place, if someone WAS obsessed with me, I'd be speechless. It'd be like, I have a fan. Makes me feel that I'm a celebrity. lol
But yeah. Obsession is OK if it has limits.

But stalking or collecting/stealing some of his personal things (like underwear. ewww) is too much. And freaky.
(^_^)Y peace.
