If you ask someone: `Do you judge people because of their outlook?', usually you can hear answers like “No, it doesn't matter for me” or “It's not important”. In those situations we should wonder why are we still taking care of that how we look like.
When we meet a new person, the first think we can notice is that how he/she looks like. Character is the most important but we cannot know it during our first meeting.
Taking care of outlook isn't a new thing. People always want to be attractive. It's connected with fairytales. In stories good characters always are pretty and handsome, and their lives are almost perfect. The bad ones are ugly, they don't have friends or happy families, and the story doesn't have `a happy end' for them. In the real life parents tell to children (for example when they are in danger) “Don't touch that! It's ugly!”, and then “ugly” means “bad”. When child grow up, sometimes he/she wants to spend time with someone who takes care of an outlook. If he/she takes care of her/himself, he/she should know how to take care of another person.
On the other hand we don't like those people, for whom the outlook is a matter of life or death.
Those rules are almost the same all over the world. It works in the same way in Europe and U.S. , in Poland and Germany. It doesn't matter if someone comes from China or England.
In my opinion it's important how we looks like, but the most important thing is how we live and what we're doing for the others. Before anyone will critic another person, this “anyone” should know his/her character, because sometimes in real world “ugly” can mean “I can be your good friend, too.”.
