I get a number of phone messages for the instructors, some of which I can respond to with no problem. Then there are others.
“This is Mohamed. Call me back.” (He might not be aware that we have an amazing number of people named Mohamed, and not leaving a number doesn’t narrow down the possible field.)
“This is Ahmed. Tell my teacher I can’t be there today.” (Again, no number, and when I mentioned the call in an instructor meeting, one of the teachers said that she had three Ahmeds in just one of her sections.)
