Who’s XXX?

Nobody enjoys being insulted.
School sucks and people are rude.
It might not help right now but when school is over you will likely never see them again.
Once we get into the real world, very few people act that way. You have more control over your environment so you are not forced to be around people you do not like.

It's probably not the words. It's the unnecessary cruelty. People who do things because they think they can get away with it, are just begging for someone to prove them wrong. In fact I'd say most of what's wrong with the world exists because of people who engage in this behavior

Oh I didn’t reed past three sentences, sorry.

life will serve them their share

Be brave and calm. If they mess with you again start thinking of how to get them back. I used to be physically aggressive with people that tried to bully me ( I am stronger than I look), you can use your own skills and tendencies. But don't be cruel, just put them in their place.
