They just refused to accept that doing anything differently than they ever had done might be good for them. But the more I thought about it later, the more I thought that I might have given him an incomplete answer. In fact some people I know are easily recognized as dinosaurs. Dinosaurs were very territorial. They did not play together well, always trying to show they were more important than any other.
Dinosaurs never see themselves as the source of their problems.
They hiss, blame, and complain when something goes wrong rather than searching for and making a correction. They only tolerated things around them that were exactly like themselves, anything not like them was evil. They also were very irritated and irrational when confronted with a new idea. Theirs was a world filled with universal truths and no opinions were accepted. They were afraid of change and reacted to it negatively, searching for reasons the change would be no good rather than finding ways to make it work.
