I've been teased &/or bullied ever since I was in school, & I hated it. I even got annoyed at being called names like "Ugly" & "ret*d."
How would people feel if they were being called names, being threatened, beat up, etc.? And even if it doesn't happen to them in the future, it could happen to their kids when they have them.
What goes around, comes around. People that have good looks always like to think that they're better than everyone & likes calling people ugly, etc. Well, they had better hope that they don't ever get into a fight or anything of the sort, because they can ruin those good looks just as easy as pie.
