When we arrived home I gave him his souvenir present (a t-shirt) and then casually handed him the book in a carrier bag. 'I spotted this at the airport; I thought you might like it.'
He looked at the package and without even opening it he said, 'I've already bought it and read it.'
When the date of publishing had been announced some months earlier, he'd set the computer to give him a reminder.
'But you don't have any money,' I said.
'I used some of the money you gave me for food.'
You can't be mad at a Son who buys a book instead of food.
