Women observe subconsciously a thousand little details, without knowing they are doing so. Their subconscious mind adds these little things together - and they call the result intuition.
It is odd how, when you have a secret belief of your own which you do not wish to acknowledge, the voicing of it by someone else will rouse you to a fury of denial.
Women can accept the fact that a man is a rotter, a swindler, a drug taker, a confirmed liar, and a general swine, without batting an eyelash, and without its impairing their affection for the brute in the least. Women are wonderful realists.
