Have you ever 'taken a break' in your office bathroom stall and have someone sit in the stall next to yours and just let it rip? I think it's pretty common. But have you bent over to take a peek at their shoe (while not moving your legs as to avoid giving away that you're peeking) and then proceed to seek out the shoe that was in the bathroom? Maybe it's just me?
Okay, it might be a little juvenile, but when I track down my target, it makes me giggle; and helps the day pass a little faster. Ah.. anything to procrastinate. So if you haven't, I recommend you try it, you know, for shits and giggles. So far this year, my record is 1 for 2.
