I had this interaction with a student today.
Student: Do you have a lost and found?
Student: I lost some glasses.
Me (already walking to the lost and found): Can you tell me anything more about them?
Student: They were wine glasses.
Me (doing a double-take): Uh...
Student: They had a wine-coloured frame.
Language is a funny thing.
It might be considered strange that a student would have a set of wine glasses in the library, but it wouldn't be that strange. Despite the ban on food, we tend to ignore students sucking on lozenges or discreetly munching an apple. But the day a delivery guy turned up with a pizza, which had been ordered by a student, has gone down in legend-- at least, for me it has.
