No worse than the helpless that are lost in this world that have nothing better to do than to go on the bart all day long. Some of it is so bad, I've got a good heart and it hurts going to SF and seeing the problems it has.
I'll tell you about a man (mid 40's) who had very discolored skin and was wearing worn out sweat pants. He stepped up to me and a female passenger and asked for booze money. You could tell in his eyes that he had given up on life, and there was a good reason for that. He lifted up his shirt to reveal a colostomy bag and several tubes for feeding. He was emaciated from whatever his condition was. I asked if he was ok living life like that, to which he responded: "If I had a fucking choice in it I wouldnt be drinking, but it's all I have besides the cancer that is killing me."
I gave the dude $10 so he could buy a fifth of vodka. I know it wouldn't help make him better, but it might of helped him feel a little better for awhile.
