A student walked into my office today.
“Can I do some photocopying?” he asked.
I looked at him blankly for a few seconds, searching his face for any hint in his expression that he had the first clue just how daft his question was.
“Yes,” I answered eventually, “if you can find the photocopier.”
My office isn’t very big, so it didn’t take him long to discover that he would be better off trying elsewhere.
