<human>: Provide a brief overview of the text.

In the country that I live in, we generally have a lot of beggars on the streets; most of which, however, are frauds. A few days ago, as I was going out to meet a friend, I saw one beggar in particular which has been there for as long as I can remember. I usually don't pay attention to him, and keep walking, but this time I saw him curled up in a corner in the fetus position, head bowed 'cause of the blistering sun, barely wearing any clothes, and holding up a sign. 

Everyone who lives here is pretty immune to the whole "my child has Leukemia and we're starving" story, because as I mentioned previously, they tend to be frauds - rejecting any sort of help you try to give them if it isn't money. But for the first time, I actually read this man's sign. It stated that he is homeless and hungry, but also that he is an AIDS carrier and is dying. It hit me pretty hard: this guy looked as if he was genuinely sick and was going to die on the streets. I felt the most gut-wrenching feeling of hopelessness, and three days after, I still feel the same way.

I don't have much money of my own, let alone some to give him shelter or anything, but from now on, every time I do go, I figure the least I can do is buy him a bottle of water and a sandwich to make him (ever so slightly) more comfortable. He always has a cup for money, but I don't have enough to give him that would actually make a change - so I figure food and water is the way to go.

Is there anything else I can do? I've never felt so upset over seeing a man in complete poverty before. I need to help him, even if it's something small.
<bot>: Noticed a homeless guy who claims to have AIDS, and looks in genuine need of desperate help. I already will buy and bring him food and water, but what else can I do? Have barely any money to spare, though.
