Right, Left, Right, Left, Right....oh crap

This evening I was walking to class and for some reason started to concentrate on my steps. And then, I forgot how to walk. My right leg suddenly start taking really high steps and then when I tried to stop I scuffed my foot on the ground and stumbled. Then I tried just walking normal but both legs decided they needed to do high stepping. Luckily by the time class was over I'd figured it out again.
