There is a difference between having "troubles" and mental illness which includes addiction.A person is blessed if they had a healthy support system to help with their "troubles" but these people dont.Granted it is a choice of sort but usually these people r far beyond making sensible choices.They likely r many many years past making a sensible choice.Its ok for people to choose not to help n this area.There r opportunities that need volunteers & people wanting to help.I dont expect u to help the homeless but would appreciate it if people would not speak disparagingly about them. it does nothing to help.If u dont approve of the lifestyle these folks r living then go read about animal welfare or how to help battered women & leave this subject alone.I volunteered one night at the womens overflow shelter one night & was overwhelmed by sadness for these women.I try to go back but i get overwhelmed at the thought.I think about how close i have come to being homeless. Its really scary.
