So...this is not exactly an annoyance. But one thing I notice about some (many?) Americans that I don't see that much elsewhere is, they are eating or drinking something all the time. 呃······其实也不是很讨厌，但是我注意到有一些（很多？）美国人无时不刻都在吃东西，我在其他地方都没见过这样的。
Like, if they go to the movies they're munching on a huge bucket of popcorn or sipping on a bucket of soda through the entire movie. 比如说，如果他们去看电影的话，他们会津津有味地咀嚼一大桶爆米花或者狂喝一大桶苏打水。
If they're walking down the street they have a Starbucks latte or a Snapple bottle or something in one hand and a phone in the other. Or they are chewing gum. 如果他们走在街边，必定会一只手端着星巴克拿铁或者斯奈普果汁或者其他什么东西，然后另一只手拿着手机?；蚴撬腔够峤揽谙闾?。
They eat in the car all the time too. 他们就连在车里也一直吃吃吃。
The excuse I've heard for this is it's because Americans are so busy all the time that they have to eat on the run anywhere they can. 他们告诉我这是因为美国人太忙了所以只能尽可能就地吃点东西。
But still...aren't people in other countries busy too? It's a bit of a puzzle.
