As you ponder, reflect in this...
Schools are a type of community.
A community, by definition, is a group of interacting people. These people, in a community interact, based on proximity.(i.e., in space, time, or relationship).*
This type of community is a social unit. This social unit shares common values. Social cohesion is the end result.
Additionally, a type of community is a group that interacts, lives(thrives), and shares a populated environment (to foster a desired interaction). A community is a group or society. A community is formed and designed to help each other achieve common or desired goal(s). The goals, as well as, the method(s) of accomplishing them, are agreed upon and openly accepted by all in the community.
