It can't happen to me

In high school girls who weren't really friends with me told me stuff they didn't wanna tell their "friends". One girl got an std the first time she had sex. I felt sorry for her. But in the back of my mind I said "that's never gonna happen to me". Why doI think I'm super woman? Why does anyone think that they can't get "it"? Bad things happen to good people who make foolish decisions. I don't think before I act all the time but I should. Being reckless isn't cool but for some reason it's fashion these days.
