What do these places all have in common?
At any given time there is an enormous range of emotion driven by personal circumstances. To the masses, there is hardly a way to detect the circumstances. In all three locations: Love, Fear, Resentment, Anger, Apathy, Disbelief, Grief and Hope are commonplace.
In a church – Love in the case of a wedding. Grief in the case of a funeral.
In an airport – Exhilaration in the case a returning soldier. Regret in case of a burdened business traveler.
In a hospital – Fear in the case of a cancer patient. Hope in the case of an expectant mother.
