Back when i was still a student ,i used to do everything alone and this was not because my friends did not want to help me but it was just my kind of life. i realized this when i grew up that i was not too social which was not bad!!. Life style discovery is the simple thing to discovery but sometimes people mistake it for wild behavior. So some people hate high noise and high music while others like it and this is not that someone is pretending but the body system itself. According to research most quiet people are usually scientists and people just took it like that but not the case .scientists usually think alot and the more you are quiet the more you will use you brain to think.
In my opinion i think every character is good if someone knows how to use it but also what hates me is that humble people are usually taken to be guilty because they have no confidence to explain and speak louder.
Equally when the girlfriend cautions her boyfriend and the boyfriend keeps quiet she will conclude he is guilty .
In that situation usually humble and quiet people are usually take guilty.
So everyone should know someone behavior before taking action.
