One of the hardest situation that I have experienced is dealing with people who are rude at times. Even if you are nice with them they might not behave the same way. They can be rude, try to dominate you. This happens in most of the workplaces. While browsing the web i came across a nice comment on blog post.
“When we were child we were unhurt by nagging of friends, as an adult we easily get irked by others behavior. ”
So what has changed when we grow up. Its our Ego that we develop. Its tough to give up the ego and requires lot of persistent effort, but this seems to be one of the way to deal with tough people.
