You can say kind things to other people, even people don't like. You might be wondering, "why should i say something nice to someone that i don't like."
Sometimes, the best words are the ones you "don't say". Don't brag about people behind them. Don't spread rumors even if you think they're true. Think about how will you feel if somebody talks u at the back. =)
