As a general rule, do not kick the shins of the opposite gentleman under the table, if personally unaquainted with him; your pleasantry is liable to be misunderstood--a circumstance at all times unpleasant.
The Master said, “A true gentleman is one who has set his heart upon the Way. A fellow who is ashamed merely of shabby clothing or modest meals is not even worth conversing with.” (Analects 4.9)
What king has he not taught state, as Talma taught Napoleon? What maiden has not found him finer than her delicacy? What lover has he not outloved? What sage has he not outseen? What gentleman has he not instructed in the rudeness of his behavior?
I should be very much obliged if you would slip your revolver into your pocket. An Eley's No. 2 is an excellent argument with gentlemen who can twist steel pokers into knots. That and a tooth-brush are, I think, all that we need.
I never cheat or steal. Also, I never wear a top-hat with a sack coat or munch bananas in public on the streets, because a gentleman does not do those things either. I would as soon do the one as the other sort of thing--it is all a matter of harmony and good taste.
