People think they're all it.

Some people really need a life.
Thinking they can boss anyone around because they think everyone likes and knows them. Well lemme tell you something.

Someone new or whatever could come up to you and say Hi wanna be friend and whatever?!... And you wont like them because u think that theyre not cool. So what if theyre starter, or look weird. At least they might be fun and nice.
I used to not like someone cause of that and then in ages everyone liked them and that person became popular.  I tried to become friends with them and they said "No. You didnt like me in the first place why should I like you know." 
So be nice no matter what. Because they Will turn out better than you someday.

It happenes in school aswell. It happened everywhere. So keep that in mind.
