Dave is Almost a Good Person

While walking around the school, I noticed a soda cup (complete with plastic top and straw) stuck in a boxwood shrub next to the soccer field-- a lazy student must have used the bush as a trash receptacle-- and so I went over, removed the cup, and threw it in the trash can (which was less than twenty yards from the shrubbery) and while part of me felt very good about my altruistic behavior, there was another part of my brain, the quid pro quo part, that was thinking: Dave just earned the right to litter (one time only) in the near future.
