This document discusses the typical stages of culture shock that people often experience when living in a foreign culture:
1) The "honeymoon phase" where everything in the new culture seems exciting and wonderful.
2) The "anxiety" stage where the novelty wears off and small frustrations with the new culture emerge as things no longer seem as good.
3) Eventually reaching an "acceptance" phase where one learns to accept both the positives and negatives of the new culture and starts to feel more at home.
The document also notes that some people may experience "reverse culture shock" upon returning home, finding their home culture dull in comparison.
