A Problem With Their Classification

(I go to college in the northeast, which has recently had several large snowstorms. The day before had been a snow-day, and more snow is due this night. I am in an early afternoon class, chatting with a few classmates before the professor shows up.)

Me: “It’s not supposed to snow until 11, but the school cancelled some of the more unimportant things starting from six onwards.”

Classmate #1: “Wait, classes are cancelled from six on?”

Me: “What? No, some events are cancelled. Sorry if you misunderstood.”

Classmate #2: “I was confused too. You said ‘unimportant things’ and the first thing I thought was ‘classes.’”
