But it is best perhaps to take in illustration some daily custom we have all heard despised as vulgar or trite. Take, for the sake of argument, the custom of talking about the weather. Stevenson calls it “the very nadir and scoff of good conversationalists.” Now there are very deep reasons for talking about the weather, reasons that are delicate as well as deep; they lie in layer upon layer of stratified sagacity. First of all it is a gesture of primeval worship. The sky must be invoked; and to begin everything with the weather is a sort of pagan way of beginning everything with prayer. Jones and Brown talk about the weather: but so do Milton and Shelley. Then it is an expression of that elementary idea in politeness⁠—equality. For the very word politeness is only the Greek for citizenship. The word politeness is akin to the word policeman: a charming thought. Properly understood, the citizen should be more polite than the gentleman; perhaps the policeman should be the most courtly and elegant of the three. But all good manners must obviously begin with the sharing of something in a simple style. Two men should share an umbrella; if they have not got an umbrella, they should at least share the rain, with all its rich potentialities of wit and philosophy.
