@Quarry Man, this isn't just an age issue, this type of behavior from others tends to spill into adult life. A lot of peeps I meet always have to be better than you and go out of their way to instill that belief. It used to bother me as well. Keep your head down and keep, keeping on and pay no attention to those peeps who think they know it all. In the long run, they usually prove that they can't do as much as they think they can do.
