Dear Queenie,
I take a class for older people at a local university along with the regular university students. Sometimes the other students will be chatting about something else while the professor is talking, which makes it hard for me to hear the professor. And then the chatterers will ask the professor to repeat what he said because they didn’t hear it.
Queenie, how do I get them to shut up and listen to the professor?—Older student
Dear Older student,
How about telling them – as politely as you can manage under the circumstances – “Please shut up and listen to the professor!”?
You might also want to discuss this matter with the professor. I am surprised that he (or she) has not noticed the problem and taken steps to solve the problem.
