http://en.wikipedia.org/wiki/Attribution_theory Psychology is something that interests me. How we attribute why people do things. Dispositional attributions Perceptual salience and attribution This makes sense if someone comes off as rude or wrongs you or others, people don't like to accept or take into account the fact that their are many other external factors that play a role in them coming off that way. Some people just assume good people never or don't do bad things. In many peoples minds if someone wrongs you or a friend they must be a "bad person" otherwise they would have never wronged you. Everybody makes mistakes we all harm people, it's a part of life. It's very hard for most people to comprehend the fact that someone wronging you may have been due to the context of their situation not purely their personality. They think "if he(or she) was a good person they wouldn't have wronged me". If you cause harm to someone you prevent cognitive dissonance by thinking worse of that person. The opposite can be said if you do a favor for someone you think better of them. Even nice, caring or just "good" people can come off or even do rude, angry, things from time to time. That doesn't necessarily make them a bad person.
