You run an errand at the post office and, on your way out, notice an unattended little stack of envelopes on a side counter in the lobby. They're obviously forgotten, so you take a peek: the first looks like a credit card payment; the others are a utility payment and something to the Disabled American Vets. One has a stamp; the other two don’t have postage.
You look around, see no one, and consider taking them to one of the clerks at the counter. Instead, you pull out your new roll of stamps and, as a little pay-it-forward courtesy, affix postage and drop the envelopes in the mail slot.
Oops, bad idea. Very bad idea.
What’s the story?
