                                     MEN VS. WOMEN

COMPARING NICKNAMES

 If Laura, Suzanne, Debra and Rose go out for lunch, they will call each other Laura, Suzanne, Debra and Rose.

 If Mike, Charlie, Bob and John go out, they will affectionately refer to each other as Fat Boy, Godzilla (怪兽), Peanut-Head and Scrappy.

EATING OUT

When the bill arrives, Mike, Charlie, Bob and John will each throw in $20, even though it’s only for $32.50. None of them will have anything smaller, and none will actually admit they want change back.

 When the girls get their bill, out come the pocket calculators.

MONEY

 A man will pay $2 for a $1 item he wants.

 A woman will pay $1 for a $2 item that she doesn’t want.

BATHROOMS

 A man has six items in his bathroom: a toothbrush, comb, shaving cream, razor, a bar of soap, and a towel from the Holiday Inn.

 The average number of items in the typical woman’s bathroom is 337... A man would not be able to identify most of these items.

ARGUMENTS

 A woman has the last word in any argument.

 Anything a man says after that is the beginning of a new argument.

CATS

Women love cats.

 Men say they love cats, but when women aren’t looking, men kick cats.

FUTURE

 A woman worries about the future until she gets a husband.

 A man never worries about the future until he gets a wife.

SUCCESS

 A successful woman is one who can find such a man.

MARRIAGE

NATURAL

 Men wake up as good-looking as they went to bed.

 Women somehow deteriorate (恶化) during the night.

OFFSPRING

 Ah, children. A woman knows all about her children. She knows about dentist appointments and romances, best friends, favorite foods, secret fears and hopes and dreams.

 A man is vaguely (含糊地) aware of some short people living in the house.

THOUGHT FOR THE DAY

Any married man should forget his mistakes. There’s no sense in two people remembering the same thing.
