Understanding

General speaking, although there are billions of people in this world, it is really hard to have someone who can understand you. Argue with people who can't understand you is pointless. They just won't understand, because they don't know what happened to you in the past, nor what have you been doing.  They just don't know why you would feel that way. They judge things according to their "understanding". Sometimes, people who have never been to some stages in their lives don't know some words would trigger other's emotion and couldn't understand it why all the sudden that person got mad at him/her. On the other hand,  People do have weaknesses, and most of people don't like to reveal that to other people. It is just really hard for people to tell all the things they have been gone through and thus some words shouldn't be said. Again, not everyone is a good listener, or even care what you have been gone through. Explanation works? I doubt it.

Everyone has something that's forbidden. Accidentally crossed that line is fine. But crossing it again and again, that's awfully mean. I wish feelings are something that people can control or be rational, so that there would be more happy people in this world.
