Never invite to dinner: those who won’t decide until the last minute; those who come more than half an hour late; those who want to bring along two or three friends; drunks; monologists; those who stay until three o’clock in the morning; those who think that conversation means having an argument; those who take a high moral tone; those who are stupid, ugly, or dull. Enforcement of these rules will enable one to eat alone every night in comfort.
