Manners are made up of trivialities of deportment which can be easily learned if one does not happen to know them.

The fact that slang is apt and forceful makes its use irresistibly tempting. Coarse or profane slang is beside the mark, but "flivver," "taxi," the "movies," "deadly" (meaning dull), "feeling fit," "feeling blue," "grafter," a "fake," "grouch," "hunch" and "right o!" are typical of words that it would make our spoken language stilted to exclude.

The joy of joys is the person of light but unmalicious humor. If you know any one who is gay, beguiling and amusing, you will, if you are wise, do everything you can to make him prefer your house and your table to any other; for where he is, the successful party is also.

People who picnic along the public highway leaving a clutter of greasy paper and swill (not a pretty name, but neither is it a pretty object!) for other people to walk or drive past, and to make a breeding place for flies, and furnish nourishment for rats, choose a disgusting way to repay the land-owner for the liberty they took in temporarily occupying his property.

Never take more than your share - whether of the road in driving your car, of chairs on a boat or seats on a train, or food at the table.

In popular houses where visitors like to go again and again, there is always a happy combination of some attention on the part of the hostess and the perfect freedom of the guests to occupy their time as they choose.

Never do anything that is unpleasant to others.
