I find that something that happens alot is people picking on other people or they make fun of something that someone struggles with. But its about things they don't even understand. Like in my school im constantly hearing about kids making fun of people cutting them selfs, which i personalty think if you have never done it or came close to doing it. Then you have no right talking about it because you dont understand the pain an emotion or stress your caused in order to do it or what it does when you do do it. They make fun of people with eating disorders or anxiety an depression i don't think you can judge if you've never been through it at all!! its just rude and insensitive.
