得服务员过来，才点的出一桌菜。

得看见火车头，才知道正在转弯。

​

From my observation, it’s difficult for many people to order food in a new restaurant, it always takes a long time to read the menu and choose dishes,  until the waiter comes to the table for the order. At that moment, under this unidentifiable ‘pressure’, people can finally figure out what to order.

​This unidentifiable sensation also occurs in another scene when we are on the train, looking out the window at the scenery rushing past us. We are heading forward is the only definite recognition, and we are not provided with anymore information. However, only when we see the carriages from the window are we presented with a solid ‘clue’ that we are turning on the track.
