Shyness in Students

When we watched the video called "Shyness" the one boy in it reminded me of myself in way that when I was young I did have friends but most of the time I liked being alone and doing my own thing. Even today I sometimes like being at home alone and having no one around me, it gives me time to just relax. I felt bad for the one girl in the video who almost had the feeling of being left out or different from the other children. It reminded me of when I drove past my home town school and seen a young boy in about grade 2 or 3 sitting in the corner of the field starring at the other kids playing soccer. I don't understand how children won't try to include others in their games at recess. I find it to be somewhat "stuck up" and feel that if they keep doing that they will turn into the "bullies" once they hit middle school and on. I like to treat others the way I would like to be treated, I don't like seeing people feeling like they are being left out. I even notice that in college some people are "stuck up" still. For example when there's partner discussions and everyone quickly finds a partner and there's one person left over,no one even notices. I find it harsh that no one will ask them to be a part of their gorup except me in that one particular class.
