First of all homeless people are scary. They scare the hell out of other people.
When you are homeless act like you are not homeless, because people are scared of homeless people. Shave and shower and don't stink, and people will ignore you. Brush your hair and teeth, and wear clothes which look and smell as neat and clean as possible. But if you don't, and if you walk about stinking and unshaven then people will be afraid. They will also be angry or annoyed or various other things. Sometimes they'll presume you are evil, proud, lazy and all sorts of other evil. Don't be surprised. Nobody can see into your mind whether you are safe to talk to.
I see quite a number of homeless people here and there, along with panhandlers who might claim to be homeless but really aren't (and a few I know it for a fact). Some are scammers, some are addicted, some are mentally ill, and some are just plain mean and nasty. Some never got a break in life; some may have been abused/traumatized. Some are veterans who should be entitled to care from the VA, but I don't know what's going on with that.
I once gave a ride to a hitch hiker, who then pulled a gun on me. Since then I have been very cold towards hitch hikers. When someone approaches me in a parking lot I give them the cold shoulder, and I hate myself for doing so. I also hate this new 'Anti homeless' architecture in cities. It is cruel and ugly and terrible, but I also wouldn't want homeless people near to my business or near to my door. The fact is, they are often crazy and dangerous.
I've picked up hitchhikers once in a while, but not in decades. I don't think I would do it now.
I think cities could at least set up some showers and toilet facilities and areas designated for homeless, if not shelters.
If nothing else, at least it would solve the problems faced by local residents and businesses having homeless people by their doors. Because they're not going away that easily, and most cities can't afford to round them up and lock them away (because if they could do that, they could afford to buy shelters).
They can try to kick them all out of town, but they'll just come back - or move on to another town. (Some cities were giving homeless people one-way tickets to Hawaii, but the Hawaiians started complaining about that.)
A girl in an enormous truck drove next to me as I was walking in a walmart parking lot. She began to talk to me about her problems. She had to leave her boyfriend, and she had no gas. I thought about it, then I quickly escaped. No telling what this girl would do. Would she scream like I had tried to attack her? Would she pull a gun out of her glove compartment? Would she take my money and laugh all the way home? Maybe she was trying to sell me sex? Maybe she really was having a hard time and just needed a little gas. I had no idea what this was about. I simply got the hell away as fast as I could.
Is it normal to walk up to a stranger to ask for rides? For gas money? I don't think it is. I think its a mark of someone who doesn't consider the feelings of others. Since having a gun pulled on me I will never risk my life again to give a ride to a stranger, and I in turn may one day be homeless, and I will understand when other people don't want to help me. I, in turn, may one day have no one to help me. That is cruel and horrible and true.
I'm reminded of this scene from the movie Falling Down (1993)
