Sometimes people can be cantankerous and not care about how rude they are being because they can't handle some situation that's in front of them- they are pretty much what some people would label as brats. A lot of this whole success in getting along with others seem to be about opening enough a pretty good deal and having a pretty decent tolerance level. Some people are just awesome at not stressing out with any situation, and these people are like my role models.
If something is missing in life and a person really wants to know, I say that it is better to just use the imagination and think about how it is in reality while doing the best to try not to sin about it and then accept it while moving on. I think that it is a fair compromise in a good amount of instances and will prevent from getting the person into unnecessary fisticuffs with others.
