Going with the Crowd
What’s going on in the average crowd? Some people are standing by themselves, wrapped in their own thoughts. Others are gathered in a small group and engaged in lively conversation. Couples may be holding hands and some may have their arms around each other. As people move through the crowd, there is a lot of bumping into one another.
News You Can Use
- Gatherings of people occur for many reasons. We wait in line for the theater or a music performance. When boarding an airplane, we stand in rows according to our seat assignment. At outdoor performances, we tend to sit apart from other people when possible because we don’t want to feel crowded.
- A crowd of strangers will usually be at a greater distance from one another than a group of friends. There is no attraction felt, so we get “our space”. If there is attraction among people, they will stand closer together.
- At times, space is limited, so it becomes necessary for people to crowd in closer together. There are more people in the same amount of space – the result is more contact between bodies, but it is transient and not the same lasting contact enjoyed by people who feel close to one another.
