I just walked past a homeless man.
(I am assuming he was homeless as he had no shoes on, dirty clothes, mated hair and was looking through a bin. )

As I past him I tried to not look at him, I didn’t want to gain eye contact.

Why?

Honestly, I didn’t want to give him any money. I didn’t want to help him. And I knew that by looking at him, and getting eye contact with him I would feel terribly guilty about not helping him. I don’t want to feel bad. So the best tactic was (is) to pretend I didn’t see him and just keep walking. Just act as if he didn’t exist.

The problem is this didn’t/doesn’t really work. I still feel terrible. This man does exist and is probably still wondering the streets looking in bins, without and shoes.
