“What excuse did the farmerette have for being rude?”
Was the “farmerette” rude? It looked like she asked for directions and was escorted to the classroom. Who knows? There might have been much more to the story than what was written. But when teachers are with their students, yes, they do have a responsibility to act like gracious adults. It sets a good example.
It was very poorly written and it's hard to comment on what isn't there.
