A Gentleman ...
Does not discuss his family affairs in public or with acquaintances.
Does not speak more than casually about his girlfriend.
Does not go to a lady's house if he is affected by alcohol. He is temperate in the use of alcohol.
Does not lose his temper; not exhibit anger, fear, hate, embarrassment, ardor or hilarity in public.
Does not hail a lady from a club window.
A Gentleman never discusses the merits or demerits of a lady.
Does not mention names exactly as he avoids the mention of what things cost.
Does not borrow money from a friend, except in dire need. Money borrowed is a debt of honor, and must be repaid as promptly as possible. Debts incurred by a deceased parent, brother, sister or grown child are assumed by honorable men as a debt of honor.
Does not display his wealth, money or possessions.
Does not put his manners on and off, whether in the club or in a ballroom. He treats people with courtesy, no matter what their social position might be.
Does not slap strangers on the back nor so much as lay a finger on a lady.
Does not 'lick the boots of those above' nor 'kick the face of those below him' on the social ladder.
Does not take advantage of another's helplessness or ignorance and assumes that no gentleman will take advantage of him.
A Gentleman respects the reserves of others, but demands that others respect those which are his."

I have mixed feelings about this... Parts of it I like, parts of it not so much. You?
