Have you ever been walking down the
street and realized that you're going in the complete opposite
direction of where you are supposed to be going? But instead of
just turning a 180 and walking back in the direction from which you
came, you have to first do something like check your watch or phone
or make a grand arm gesture and mutter to yourself to ensure that
no one in the surrounding area thinks you're crazy by randomly
switching directions on the sidewalk.
