"Thank you" I said. It's nice when the people you love share your opinions.

I looked at him with something close to shock. My father and I have a very satisfactory system in place, based on the unspoken agreement that I won't tell him about my love life and he won't ask. All that sort of carry-on is Mum's department, and she advises Dad on a need-to-know basis. "Um, yes," I said.
"Very good," said Dad and, clearly appalled at having strayed so far into this emotional minefield, he began to brush his teeth with most unnecessary vigour.”
