Like someone who stutters he has trouble getting words out and forming sentences-nervous. But it's not stuttering. And he doesn't put things in proper perspective in that he goes to great detail on something that most would take care of in a flash. This wastes everyone's time and annoys the managers. He moves around in haste unnecessarily (I've seen this in others who are nervous and use the haste to block out fears.) But who can classify mental conditions? Next year there will be a new interpretation a new name. I do this because how can people be helped if you don't try to understand them?
