They are some of those strange observations the foreigner makes in China:
Guy and girl sit next to each other in the park. They coddle each other, obviously very much in love.
Same people, same place, half an hour later: she has her back turned to him, sullenly plucks on some leaves, obviously irritated. He stands there, dumbfounded, obviously not quite knowing what to do.
Guy and girl walk down the road. She suddenly stops, pouts, “huhn”-s at him; he has to scramble for words to convince her that she’s the best and prettiest, and worth everything and anything, before she even takes another step.
Oftentimes, many such behaviors found widely among East Asian girls, along with a deep-seated fondness for everything cute and girly (not least in clothes and accessories), make their foreign observer incredulous.
