Try a simple experiment. Ride in an elevator and closely observe the behavior of everyone in the elevator with you. Write down in a notebook such things as how far away people stand from each other. Note the differences carefully, even in estimated inches. What do they look at? Do they tend to stand in the corners? Do they converse with strangers or the people they are with? If so, what do they talk about?
