I sent a colleague a question by email, and yesterday, he replied. The fact that there was an intervening period of three and a half years doesn’t seem to have phased him at all; it was not, in fact, worthy of mention in his response.
It reminded me of a Physics teacher I had at school. An excellent teacher, but known for being very slow in returning marked homework assignments — if, indeed, they came back at all.
One day, as he was handing out some marked scripts, he said, “Ah, this one’s for Cardozo”, and handed it to my classmate, who was about to protest that the script wasn’t, in fact, his… when he recognised it as his father’s handwriting.
