This has happened on a few occasions, I’ve always fed and bathed the person, on a few occasions,I’ve let the person stay with me for a little while, and once I dated a guy for a little while.

This has ended with mostly positive results. And these people didn’t really come knock on my door (we usually met out-and-about).

There are some cultural differences here that affects the equation. If homelessness is taken care of that doesn't mean there are no people on the streets. There will however be a a certain "enrichment" in what type of people are there.

Our constitution demands that everyone must have a life worth human dignity. If somebody looses everything, gouvernment provides housing and funds for minimum standards of living.

So for that reason, only ones that are on the streets are the ones who can't/won't take care of themselves, even if these things are given to then, but are not so far gone they could be institutionalized. Everyone is still free to get hammered and be on the streets.

Very often these people have long history on substance abuse and have degraded to a level of a child. Police often picks them up, so they can be washed, because they often soil themselves. They are not dangerous, because then they would be institutionalized, but they are very smelly and often vocally abusive.

Would I open my door to these people? No.

I would give then food and water if needed, but these are not things they ask for.

We bring food sometimes to the local homeless guy but he doesn't seem to want anything else.

This answer for me would really depend on a lot of factors. I don't want a homeless roommate who won't leave and can't work, don't want a mentally unstable person in the house with my daughters. So random guy probably not. I'd bring him food and a gallon of iced water and say I could not let him in. If it was the guy we know from under the bridge, and husband home, probably would let him shower and give him some of husband's clothes to wear, sure.

But we HAVE had homeless people stay with us for a time if we knew them, quite a few times. Wandering guys who just didn't live anywhere. Couch surfing people.

I'd wash his clothes, too.

I'm not a hairdresser and wouldn't have confidence trimming a guy's beard. Other than that, I'd let him in, get to know him a little, maybe give him a salad with water, and yeah the shower would be on the house, you think I'd charge for a scent cleanse using Earth's most abundant resource? I just hope he brought clothes, unless he doesn't mind wearing women's clothes.

I am skeptical on letting my friends in my house. I am not going let a random person with high odds of having some sort of physical/mental issue in my house no thank you.

Will I help? Absolutely. Just in anywhere that isn't my house.
