What are three things that homeless people need?

That depends on their situation. Many homeless persons, after being subjected to a depressing state of mind, find themselves abusing illegal substances. So, if a person is on drugs... What does he want? Well, drugs. Now, I am not saying that all people who find themselves homeless will wind up on drugs. I am simply stating that it depends on their situation. If they have no where to go because they didn't pay their rent and were evicted; they will want money to pay rent. If they were kicked out of their house after their mortgage wasn't paid; they will want to get it paid. If they are homeless; they want food. If they want food they need money. It's a bad place to be but it's reality. The person may want to escape reality. They want drugs. It's a never ending process and that is why the status quo, at present, is flawed.
