You Genuinely Enjoy Drinking Hot Water and Looseleaf Tea
The occasional glass of hot water is nice, isn't it? Especially during a China winter, it warms you up from inside out. On the other hand, if you find yourself drinking hot water during a China summer you've gone full native.
And looseleaf tea (unless it's in one of those thermos with the strainers) is simply not practical. The leaves get in the way and that herbal bullshit simply does not contain the caffeine a red-blooded American needs to get through his or her day. What would your grandfather say if he caught you with that?
