Otters

The teacher said on the report card that Bobby doesn’t play well with otters.
Otters? Doesn’t she mean others?
I scheduled a parent-teacher conference for the following Tuesday, and I was horrified to find the classroom covered with blood and hair and gristle.
“What kind of slaughterhouse do you run here?” I exclaimed.
“It’s your son Bobby!” answered the teacher. “Didn’t you read my note? Your little monster doesn’t play well with otters.”
“Otters?” I looked around. “These are dead otters?”
The teacher nodded.
I apologized to the teacher, grounded Bobby for a week, and suspended his annual zoo membership.
