Reverse Culture Shock

Moving to China, I expected differences in culture and customs. I expected that when I returned to the USA, there would be a few American customs that I too would notice and feel, but I never expected that there would be SOOOOO many!!!! The degree of reverse culture shock that I am feeling is pretty shocking. Having lived in America for over 20 years, I assumed that America would be familiar. With the click of my fingers, I would be instantly changed back to being an American. Instead I am realizing that I am super flexible and have absorbed a lot of Chinese culture and customs making American ones feel strange. I am feeling more like an international citizen who has the tools to observe different countries' customs, make comments about them, and then adapt to them.
