Most of what a household appliance store sells is meant for the end of the day. People rarely buy a fan for the morning. They buy it for the hour when the house goes quiet and the head is still busy with whatever the afternoon left on it.
We sell fans, televisions, small radios and a fair number of armchairs, so we spend a lot of time listening to customers describe their evenings. The stories that come up most often from people somewhere past fifty are not about the machines. They are about the habits that settle around them: the room that gets cool and dim at the same hour, the station that plays while the dishes are done, the chair where a book waits on the arm.
This little notebook takes three of those objects out of the box, one at a time, and writes down what we have heard and read about the evenings around them. None of it is a promise. All of it is the kind of thing you can try tonight and judge for yourself, with your own doctor having the last word on anything that touches your health.
