I'm a homeless transient. One constant I've noticed is that around the downtown area in all medium sized ( population 100,000 + ) cities or larger, there are large groups of teenagers that hang around at night, goofing off and shooting the bull for hours. Don't they have any work to do? Don't they have anything better to do? Another phenomenon I've noticed is large groups of old men who shoot the bull all morning at fast food restaurants. I know that most of them are retired, living off pensions so they have a lot of free time, but don't they have anything better to do? What is the purpose of this?
