I don't see how anyone could not think. ( I mean, obviously I do, I see it, but I don't understand.) I come from a place (personality-type, upbringing, etc) of deep and constant thought. The need to examine, test, reflect, expand, improve, break-down, grow, change, experiment, compare, contrast, and on and on and on...
As one of my friends once said, "Everything you do or say is always for a reason."
So it can just flabbergast me sometimes that people simply take something presented to them, and then turn it into a hill they'll die on in what (rather indelicately stated) is a brash act of foolishly brazen ignorance.
Anyway, momentary rant aside, please people...use the brain God gave you. It will change everything.
