I dislike modern memoirs. They are generally written by people who have either entirely lost their memories, or have never done anything worth remembering.
Curious things, habits. People themselves never knew they had them. [Witness for the Prosecution, also published in The Hound of Death and Other Stories.]
When we are young and again when we are old, we depend heavily on the affection of others. Between these stages we usually feel that we can do everything without help from others and that other people's affection is simply not important. But at this stage I think it is very important to keep deep human affection.
