Pardon my comments in English. This is called "excellent acting skills". This husband is actually "Big wisdom", not just smart, not just intelligent but "pure wisdom" because he realized that his wife was laying a 'trap' for him to step into. If he answered 'yes', his wife will accuse him of evil intentions toward her female friend. If he answered 'no', his wife will accuse him of lack of basic human sympathy and decency to help her female friend in need. Therefore he bypassed the original question through diversion. At the end though, his wife ran out of patience and hit hime anyway. Morale of the story is for "a guy to choose his wife wisely". Just my 2 cents. Thank you for sharing.
