Is insulting community really so terrible?

I was in Open Art Studio, one of my electives. The teacher was talking about how there was only one more class because the next one would be replaced with community. Community (formerly known as B block) is a completely pointless class that replaces an elective every once in a while.

Everyone in the class was upset. We were all saying "Why don't we just skip community?" and "I wish we had more Open Art classes."

One person said, "But community is completely pointless!"

Suddenly the teacher's face became surprised and astonished. She stared ahead, her mouth open.

Nobody could figure out what was going on. Was insulting community really so terrible?

We all looked at each other, and people started to laugh. The teacher was still frozen - her astounded face becoming very funny. We still had absolutely no idea why she was so upset.

Eventually the teacher explained. "My plants are dead," she said.

We looked around the room and, sure enough, every plant, of which there were many, was dead.
