I've been homeless and working at the same time. The main problems are the cold and washing. Having a job is easy enough as long as the people don't know you're homeless. I managed to feed myself, pay for college, work, and keep my car running...and even post on the old ASO...all while being homeless. And only one other person knew about it. Was it pretty miserable? YES. But I read plenty of books, kept myself clean, and made the right decision. I could have begged money and crap, but I didn't. Instead, I chose to live with what I had, which was enough money to pay for food, one book at college (Classes were hard without the books.), showers, and fuel, but not enough for rent.
Oh, and actually the people at my college knew I was homeless and decided to cancel all of my financial aid. And then they told me maybe college wasn't for "my sort." But I showed them. Straight As again baby.
Anyway, that's a long story. Hope that slut gets run over by a herd of gorillas.
