Is it just me or do some people spout knowledge just to sound cool or make themselves sound more interesting? People think I didn't understand a topic or need to have something explained to me. Becasue they seem to know so much. It seems like some lack confidence, so they have to flaunt there knowledge of a subject. Even worse is when they think you know nothing of it and they feel they need to explain something to you? I admit I try use knowledge that is applicable. I know as a teen I was bit of of a know it all. I think most teens do this for so time and then grow out of it. So dose anyone else have this problem with people who just think they know everything and they are so much better than others? Whats worse is some people to think this makes a person cool.
