"Why would you do that JB?" you might ask.
Well, if you know me, you know that I am tall, and that most of my height originates from the legs. So, when the legs are responsible for above-average height, of course the gait's stride is much faster than your average fellow's. It's how I was made, the way I grew, predisposed by my genes and possibly childhood diet without a doubt.
When walking in enclosed and crowded spaces, I must exert a directed mental a effort to shorten the distance between steps so as not to run into all the slow walkers out there, which I sense is great and powerful number. Said in another way, one could say that on the normal probability distribution for slow walkers, I am most likely in the bottom fifth percentile. The exact inverse is also true.
Returning to the present state of affairs (having illustrated my condition to satisfactory comprehension), we have myself tailgating little-big Miss. -Who, at the very last moment, after veering right, comes to a halt, hovers for half a second, then swerves to the left to finally choose her seat. Seems like a pretty normal thing, right?
