Hi there,
I did a quick reply but I'm not sure if it worked - but here is what I think.
There are always going to be people out there that are like that- as the world is a diverse place and it takes all sorts. Sometimes it is the competative nature of people, sometimes they are not even aware that they are like that. I try and keep out of there way and not be like them. I make an extra effort to be kind to people or do something nice for someone, to counteract it somewhat.
