So today in class we had an exercise where the students had to read letters to agony columns and offer advice to the authors (to practice the Subjunctive.) One of the letters was by a young man who was jealous of his girlfriend (for absolutely no reason) and kept trying to prevent her from talking to or spending time with any other man.
What shocked me was that some of the students advised this man to spy on his girlfriend or follow her around without her knowledge. And these students were all male. They thought the advice was funny.
