We have a propensity to thinking after we see or understand one cause of an effect. Almost everything, like why did angela just get a little minnie can of di coke out of the refrigerator, is there one cause, or is it m causes? It's hard to even think of a single phenomenon or human behaviour that doesn't have many causes.
Why are humans so eager for magic-bullet solutions? Can you explain how a pen works? And how does Angela feel about being forever branded “the grit lady”?
