There is a woman who begs in my neighborhood, sitting outside the subway station on a milk carton. The local stores give her free coffee and she buys cigarettes, or bums them, and is constantly smoking. I'd say she's in her sixties but it's hard to tell. I was informed by a reliable source that she owns her own home. She has obvious mental problems, not severe. She engages in conversation, and has a few "regulars" she's involved with.
Now, I'm not complaining, but I'm a low-income individual, although I have a middle-class appearance & live in an (inherited) coop. My son gave me his great fear which is: If I ever become "mental" I will do the same thing for extra $ and social company. Gosh, thanks, son.
