That's an interesting question.

I've spoken of it a time or two with various people and I heard an interesting take on this doing of good and making of people smile.

Some won't talk of it. They do it, but all anonymous and stealthy like. Some of them will even deny having done one of these good things because, and here's the weird part, not because they feel bad about it but -imagine zyther noise modulating here- because they feel it makes less of the gift if credit is claimed for it.

Heck, if I ever did a nice thing I'd surely take credit for it.
