If there were more people who would do what you did, this world would really be a much better place. To have people who care about each other just doesn't happen like it used to or like it should.
We saw a man at McDonald's one cold day with a blanket wrapped around him. I watched as he counted his change to see what he could afford to eat - he only ordered a cup of coffee. Then told my DH when he came back with our food. When we left, my DH took a bag of food to his table and told him someone left it for him.
