The Son rang today and had a good chat with his father. They talked about surfing: wetsuits, surfboards, waves, breaks... There was a mention that he was working on an essay at the moment, but that was the gist of the (long) conversation.
That is not at all the conversation he might have had with his mother.
She has all kinds of questions. What is he eating? How is he getting on with his work? Has he had any essays marked yet? Does he have any holiday work fixed up? How is church going? Does he know when he is coming home?
Pragmatic questions. I would probably not dare ask them all - it would seem like an inquisition. He'll tell me, in time. I know which conversation he would prefer to have.
