The MC of a story took his girlfriend to a dance. There was an auction, in which girls were expected to bid on boys; the details of why are too foggy for me to remember; maybe a benefit. In any event, his girlfriend public embarrassed him by declining to bid (or may it was to underbid) for him at the dance. I believe they were probably in high school.
The details provided above are from a dim memory, and may not be precisely as I described.
Anybody know the name of the story?
