DAY TWO - MORNINGから引用します。
‘I’m proud of you. A good son. I hope I’ve been a good father to you. I suppose I haven’t.’
‘I’m afraid we’re extremely busy now, but we can talk again in the morning.’
My father was still looking at his hands as though he were faintly irritated by them.
‘I’m so glad you’re feeling better now,’ I said again and took my leave.
On descending, I found the kitchen on the brink of pandemonium, and in general, an extremely tense atmosphere amongst all levels of staff. However, I am pleased to recall that by the time dinner was served an hour or so later, nothing but efficiency and professional calm was exhibited on the part of my team.
