Working at the Uof Chicago saw this middle aged guy looking thru garbage cans in the plaza in front of the hospital.This one summer day with everyone outside,doctors,nurses,construction guys,this guys comes along doing he usual well it's hot out. I offer the guy a cold can of pop.He said I'll give you a pop motherfucker and takes a swing.I turned him around and booted him in the ass but,it could have been a needle,knife,anything.Homeless,vagrant can't tell mental? Can't tell.What shocked me when I went to Henderson Nev. was the practice of people standing outside home improvement stores so someone will take them to there home to do work! Are you kidding me,I was stunned crazy poop.
