What I will Never Understand About the Chinese Part 2

Here is part 2 of the things that I find most confusing about Chinese people: I cant understand -how they screech into cell phones seemingly unaware that it does no good vz the quality of the call, but annoys the heck out of the rest of us -can pick their nose openly on the subway as if they were in their own little universe with no sense of shame -cannot understand that one arrow button is for going up in the elevator and one is for going down. If you look before the doors open, the elevator will tell you if its going up or down thus alleviating their constant need to enter the wrong elevator -fear of escalators, they seem to want to leap from them as it approaches the last few feet -fear or ignorance of almost all electrical equipment, minus cell phones -why do they take 15 minutes to order something as simple as a glass of tea -why they dont walk the extra ten feet to use a public toilet (and no its not a population thing, just because they have 22% of the worlds pop. its no excuse)
