“Were headed for collapse, if you want my opinion, Missy. I can see it in the fallin off of the quality of vagrants. There was a time you could find real good company in almost any jungle youd pick, men who could talk, men whod read a book now and then; and now, what do you find, a lot of dirty little guttersnipes no decent tramp would want to associate with.
