answer:Help him. Why? Because he’s a human and deserves compassion. Should you be the one to help him? I don’t know. I don’t know what aid you could offer him. If you feel secure, you might try talking to him. Ask him if he wants you to look up a homeless shelter for him. Your talking to him might be the only interaction he has with another person all day. Most people who live on the streets are utterly ignored. Personally, I give money to beggars and homeless people. I don’t care what they spend the money on. If they buy booze, so be it. If they buy food, so be it. It’s not my place to judge. If you live in an area with resources to help the homeless, call them and ask them what you can do for him. Finally, if he is a genuine threat to your safety, call the police.
