Aren't perspectives interesting? Say a bully trips someone in the hallway, and gets a laugh out of it and it doesn't affect them and they think little of it. Well, the bystander gets upset that that has happened and then let's it be while the person getting bullied commits suicide just because a bully had the nerve to trip them. This is serious. Little things that you do can impact a whole group of people whether you believe it or not. Don't bully someone as "a joke" because it might mean more than a joke to them.
