When the feast/dinner is over, you will have found all its demerits/ defects. Then, delight turns into anger, praise into complaint, and a nodding head into a shaking one. This is because：first, when you begin to eat you are hungry，and when you are hungry even husk/chaff tastes sweeter than honey； whereas when you are full, even honey does not taste sweet at all. Second, when you arrive at the restaurant, and when you pick up the chopsticks, everything there is new to you. A newly built latrine smells fragrant for the first three days. This may be called the defamiliarization effect.
(意译)
We should not be too romantic in terms of interpersonal relations. We are such interesting beings that when we meet someone for the first time, we notice only his/her merits. This is quite like having dinner in a restaurant. Usually the first course or the cold dishes leave us a good impression. And we also praise the first two main courses. The more we have, the calmer we become. By the end of the feast/dinner, all the demerits/shortcoming of the dishes are found out. And delight turns into anger, praise into complaint, and approval into disapproval. The reasons for the change are：first, when we begin to eat, even husk/chaff seems sweeter than honey as we are hungry; whereas when we are full, honey does not taste sweet at all. Second, when you begin to eat upon arrival, everything in the restaurant appears new，even a new latrine smells fragrant. The defamiliarization effect, isn't it?
