A girl who must have been about 18 today asked me how many feet were 72 inches. She really wanted to know. She had a catalog in her hand. I guess she wanted to order something that was that tall, and she needed to know if it would fit in her house or whatever. How many people do you suppose don't know the answer to the question? Do you suppose it is different in Canada or England? Do you think they know how many decimeters in three meters? My experience is that they know how to measure in feet and meters better than Americans. But I wonder. I have not spent that much time anywhere.
