Something people, myself included need to realize is we never
know what goes on in other people's lives and minds. No
matter how well we think we do. We judge people before they even
open their mouth to say "hi." This means we need to
think before we say something cruel to them, because
words do hurt.
So, it just takes one word to hurt them more than they already
are. Basically, what I'm saying is think before you pick on
put them down.
