"I've a nephew in his 20s who does this and has for years. He eats garbage, is dirty, smelly, and probably diseased. When he gets tired of riding the rails or the weather is too cold, he returns home to his bed, food, tv, computer and games. He does no or little work, receives his $200 food stamp card, begs on street corners. He also fancies himself a musician as he carries his guitar everywhere and know three chords, but can't carry a tune. He wants to be a chef because he can fix up dumpster tossed restaurant scraps into something even dogs won't eat. My nephew is also just on north side of sanity and mental health. He's a chronic drug user and smoker, but doesn't drink alcohol because that leads to alcoholism. He was once a kind, loving, industrious, and intelligent kid. Now, he's a lost case and his vagabond friends, whom I've met, are just as useless and worthless as my nephew. We love him and we're afraid of him."
