and this something is mostly what normal people tend to think as normal and true....

e.g. the chinese ate bird`s nest... and to the west? "eww.... you ate bird`s saliva? that`s disgustingly stupid"

eg. the french delicacy which is goose`s kidney(correct me if i am wrong) and to the asians, it is only cheap stuff and consider french to be stupid to consider such as precious things....

p/s my american friend told me this... when I cooked and we use chicken bones to cook soup, and as usual, like chicken essence would come out and we drank it, and my american friend saw it.. he reacted.... "What the..... you guys actually drank it?? the juice?? that is sooo gross"
