Yeah, I know what you mean. I had some qualms after starting this, that people would think I was mocking the mentally ill, or having laughs at the expense of people who are just barely hanging on by their fingernails. That wasn't my intention - I'm fully aware that many of the "strange characters" roaming around on the streets are in desperate need, and I don't mean to be insensitive.   I'm just sort of fascinated by people who actually howl at the moon, who step outside of the normal boundaries of what is considered 'acceptable' behavior - I'm not of course referring to psychopaths and sociopaths, but to people who don't behave "like everyone else", whatever their reasons, and don't hurt anyone.
