Culture shock begins with the "honeymoon stage". This is the period of time when we first arrive in which everything about the new culture is strange and exciting. We may be suffering from "jet lag" but we are thrilled to be in the new environment, seeing new sights, hearing new sounds and language, eating new kinds of food. This stage can last for quite a long time because we feed we are involved in some kind of great adventure.

Unfortunately, the second stage can be more difficult. After we have settled down into our new life, we can be very tired and begin to miss our homeland and our family, friends, pets. All the little problems in life seem to be much bigger and more disturbing when you face them in a foreign culture. This period of cultural adjustment can be very difficult and lead to the new arrival of rejecting or pulling away from the new culture.

The third stage is called the "adjustment stage". This is when you begin to realize that things are not so bad in the host culture. Your sense of humor usually becomes stronger and you realize that you are becoming stronger by learning to take care of yourself in the new place. Things are still difficult, but you are now a survivor.

The fourth stage can be called "at ease at last". Now you feel quite comfortable in your new surroundings. You can cope with most problems that occur. You may still have problems with the language, but you know you are strong enough to deal with them.

There is a fifth stage of culture shock which many people don't know about. This is called "reverse culture shock". Surprisingly, this occurs when you back to your native culture and find that you have changed and that things there have changed while you have been away. Now you feel a little uncomfortable back home. Life is a struggle!
