One cannot reason someone out of something they were not reasoned into. - Jonathan Swift
From the VMI (Virginia Military Institute) Code of 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; nor 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.
