Another one just came to me, as I witnessed it yesterday on the train. A homeless man was walking down the train aisle, shaking a handful of coins and asking people for change in a long drawn out plead.

Everyone stared deeper into their phones until he went away, but when he came back a woman with a child handed him some change and he walked on without thanking her.

The kid asked "why did you give him money mummy?" and her response was simply "you see homeless, you give money" and that was the end of it. I just liked the implicit matter-of-fact decency in which she lived her life.
