I think we all have a social responsibility not to be mean to each other. I know that there are extenuating circumstances and that people's definitions of mean can vary, but overall, I think our interactions with each other should be cordial, if not pleasant. Part of being an adult is understanding that even though you dislike something about someone, you don't have the right to intentionally hurt them. It's (unethical) one thing in elementary school when you decide you don't like someone's shirt and tease them about it, but it's entirely different when an adult does something like that. Why would you want to upset someone? What is going in with yourself that making someone else feel bad makes you feel better? Is that all there is to it?
