Signs you've acclimatised to being in China

You stare at foreigners

You never wait for the green walk sign at street crossings, and sometimes you even cross before the Chinese people

You return to Shanghai (which you thought was CRAZY at the beginning of your trip) and it seems quiet, dead, and very western

It doesn't really phase you anymore to pee in a stinky squatty potty where the door to the stall is a 4-foot high piece of plywood that you prop up in front of you.

When you are four centimetres from being hit by a speeding taxi and jump onto the sidewalk only to miss a bike by about 2 centimetres, you just dodge the bike and keep walking. After all, you didn't actually get hit, so it's not a big deal.

You taste tea and can tell that it is cheap tea.

You don't feel bad bargaining something down to a tenth of its asking price, and you allot at least 30 minutes for buying anything since it requires a lot of bartering. You see other foreigners watching you in amazement and then they jump in after and say, "I'll take one too!" because they think it is such a great price!

You start to be grossed out by western-style toilets, because people actually sit on them. Yuck.

It seems strange to be somewhere and see less than 10 people around you.

Tones in Chinese don't seem like a complete mystery anymore, and you can hear the emotional inflection when they talk. You can also tell the difference (sometimes) between angry shouting and the normal decibel level of Chinese speech.

You become a connaisseur of air quality differences, and seeing a blue sky can make your day.

You freak out when you see food for 30 yuan (about $4.50 Canadian) because it is so incredibly expensive!
