I think that sometimes we say things without even thinking about how it could affect someone else. We don't always know what's going on in their life, so something we say may set them off. Usually it's not meant to hurt them or offend them, but it happens. Most of the time, if it happens the other person will tell us and after we may re-think our actions. Most people need to think before they say things. Words are very hurtful, even if they aren't meant to be. One wrong thing said could affect a friendship/relationship with that other person. Basically, I think most people's intentions aren't meant to be bad, but sometimes we aren't thinking when we say things.
