俾面(face-giving)

Imagine u go to someone's house for dinner. The host spend a whole day cooking the lousiest food just for you. the host  stare eagerly into your eyes and ask with high expectation, 'how ? how? is my food good or not?' forced by the situation u always answer : 'yes' irrespective of the taste of the food.

based on the above analogy it seems that when ppl commented 'good, good' or 'very nice' on your blog, u should be not be overly flattered as the compliment may just be a show of what in cantonese called '俾面' (face-giving).
