if you decided to be a guest in a Chinese family, please arrive in time and bring a god damn gift. Nomally they will invite you for food, please use chopsticks in the main dish and never mind other peoples' saliva. We do share food with all the people on the table. Let the old eat first and let others know you like the food, but never fish any dish like some moron told you, the host will be embarrised to think they provided insufficient food. After the meal, remember to sit for a while but not for too long. Cause you know, Family is an F word.
