"Some things in life are simply meant to be left alone, requiring no interference because they take care of themselves and wait to be appreciated or understood. An example given is America, which holds its own mysteries and complexities that may unfold in their own time."
"On the other hand, some things are better to be ignored or left untouched, especially if they are unpleasant or harmful. This is illustrated with the metaphor of a dead rat hidden in a closet, symbolizing things that are better off undiscovered or left in the past."
