Learning that people aren't what they appear to be, situations are much deeper than what's on the surface, and visions are flawed is a phenomena that most of us encounter daily. And when faced with the opposite of what we thought was going on most times seem surprising, it really only informs us of our biases, preconceived notions, and the stereotypical nature that festers in all of us.
After I all but confessed my ignorance of some things, I can remember my father saying many times, "That's what you get for thinking." Though he never told me exactly what that meant. I get it now. Thanks daddy!
