Judging A Book By Its' Cover.

I don't know why I do this all the time, But it is difficult not to.
Everyone does it.
They look at you and then judge you by the image that you present yourself in.
It could be the human instinct in trying to seek people who fit their levels, people who fit their category and those who fit their personality. I ponder the fact that it is highly important that a person fits your personality, if not it would be difficult to get along. However, how can we tell by a quick glance.
Isn't it a bit unfair as you could misjudge.
Seeing a person once and judging is one thing I would like to avoid in future, as those you misjudge could be those you get along with most however false that sounds.
But it is life. We should know a whole load of different people, and judging is not the way to go.
