If you were to see a man out like the underground man just walking around on the street and he started to talk to you how do you think it would go?
I'm going to paint a picture for you; there is a man in the corner of a restaurant sitting alone, hunched over in the darkness. He seems lonely so you go over there to talk to him. He sees you and says hello, but then immediately breaks eye contact and mutters something out of anger for doing so. You talk to him for a little bit and after a while he seems almost overeager just for talking to someone. He follows all of the points he makes with some sort of retraction such as, "that's not what I meant", "I'm only joking", or then again "I could be wrong" as if he is afraid you will leave the table or laugh at him for his beliefs. As the conversation progresses he becomes more and more aggressive and starts to finish your sentences for you and assume he knows what you are talking about. He starts to get angry with you for no reason and has snobby retorts any time you make a point. Finally, toward the end of the conversation he is extremely agitated and acts as if he is upset with himself but making excuses for it, and blaming you for all of his problems. When you at last try to reconcile with the poor fellow, he breaks off any connection he had with you and storms off cursing under his breath either talking to you or himself.
That is how I would envision an encounter with the Underground man (or someone like him) what do you guys think he would be like?
