My son and I went to Russia about 6 years ago. We visited a school to drop off a load of school supplies we had carried and my son was invited to spend a couple of days in the English classes. The teacher asked the class, "What is the most convenient way to travel." The answers from the students were walk, bus, and bicycle. My son told them, "You're crazy. The most convenient is car." The class just stared at him. He said, "You know. Just go out the front door, get in your car, and go where you want." It was then explained to him that only 2 out of the students families had cars and they didn't use them much because of the cost of fuel. The class found it shocking that we had 2 vehicles when only one in the house could drive.
For my son, it was a real eye opener. :shock:
