When we see a man or a woman we look at the faces and clothes. If we see a beautiful face we consider them beautiful too. But when our acquaintance is continuing we begin to notice another things. We can see good or bad character, good or bad deeds. And when a deeds are constantly bad, we do not see a pretty face now. For example, the pretty boy beats a dog or a cat. Do you look at his face in that moment? I am sure he is ugly. And Mother Teresa was not pretty, but her heart was really beautiful like her soul. So we respect her much more than any of hollywood's cuties.
