My friends are all broad-minded, and well educated, but we do not keep a record of our conversations. The reason for this is (1) we are too lazy, and do not aspire to fame; (2) to talk gives us pleasure, but to write would give trouble; (3) none of us would be able to read it again after our deaths, so why worry; (4) if we wrote something this year we should probably find it all wrong the next year.
