Avoiding Glances

I'm confused as to the reason why when people are put in a room together, they avoid eye contact. They avoid any type of communication whatsoever. I don't understand why people are afraid to speak up and be friendly. I would love to introduce myself to any stranger* that I just so happened to be in the same room with. We live in such a fast food type world, and I don't know about you, but that scares me.
I read an article and watched a video about how people react to a "stress" type situation.
Two actors, a man and a little girl, would act out a kidnapping scene in the middle of the street. They did this to test who would stop and help the little girl. Almost none of the people stopped. It interfered with where they had to be, so why should they stop?
This is a very upsetting circumstance. It tells me that the majority of the people in this world are too busy to help the common good. I understand that the people could have been scared that the man would have hurt them if they got involved, but in the long run, when it comes to warping a life in such a way like that, I definitely believe that a few hits are worth saving someone.
On another note, at the end of the video some men stopped and tried to help her. This was exciting for me, it gave me a glimmer of hope for humanity. It made me want to go out and do something to stop it, and I swear I will one day. Anyway,  just think about it, and have an amazing day. :D



Stranger*- not the creepy kind that you've been warned not to talk to.
