A gentleman never discusses his family affairs either in public or with acquaintances, nor does he speak more than casually about his wife. A man is a cad who tells anyone, no matter who, what his wife told him in confidence, or describes what she looks like in her bedroom. To impart details of her beauty is scarcely better than to publish her blemishes; to do either is unspeakable.
No gentleman goes to a lady’s house if he is affected by alcohol. A gentleman seeing a young man who is not entirely himself in the presence of ladies, quietly induces the youth to depart. An older man addicted to the use of too much alcohol, need not be discussed, since he ceases to be asked to the houses of ladies.
A gentleman does not lose control of his temper. In fact, in his own self-control under difficult or dangerous circumstances, lies his chief ascendancy over others who impulsively betray every emotion which animates them. Exhibitions of anger, fear, hatred, embarrassment, ardor or hilarity, are all bad form in public. And bad form is merely an action which “jars” the sensibilities of others. A gentleman does not show a letter written by a lady, unless perhaps to a very intimate friend if the letter is entirely impersonal and written by some one who is equally the friend of the one to whom it is shown. But the occasions when the letter of a woman may be shown properly by a man are so few that it is safest to make it a rule never to mention a woman’s letter.
