don't you have people who pass you by with nose held high ? You know they act like they are superior to you judge you but they themself have problems of their own in their life.
Self-confidence is a good thing but sometimes it,s too much some act lhink way too highly of themself. They have very little standars for themself but very high standars for others.
It happened to me a girl who judge me. Though i am not interested in her romanticly in anyway. I am into her cousin. But she talks thrash about me but i found out that she made a scene to one of her friends becuase her friends would get out together and do things and not let her know. And she made the crisis over facebook above all things. Her friend were saying that it's her who does not integrate well and things like that.
Don't let peopl judge you sometimes they can't even do better in their own life.
