At the meeting I attended recently, I noticed that one of my colleagues and his elegant wife were wearing their glasses on chains. They're a decade or so older than I am, but it occurred to me that now I'm in my forties, I may have achieved the age of "glasses chain wearing" majority.
Am I old enough to start wearing my glasses on a chain?
Settle down, whippersnapper. You've got to put in another decade yet.
You have grey hair and you forget where they are when they're on top of your head, so yes.
