1. Statistically-speaking, the population of a typical high-school is a representative sample of the community in which it is located.
2. Accordingly, the persons and behaviors encountered there are normally representative of the community in which the high school is located.
3. It seems (although, I know of no formal study) there are significant similarities concerning the kinds of persons and behaviors encountered in most high schools.
4. Therefore, it can be predicted that the kinds of persons and behaviors encountered in high school are representative of the kinds of behavior one will always encounter in life.
5. In some circumstances, as persons age, they have more opportunity to select and determine which persons they interact with directly on a regular basis and, for this reason, some kinds of persons and behaviors may be encountered less often, but they are, nevertheless, still likely to exist in the general population.
6. I would have preferred to realize this earlier in life but am pleased to know it now.
