Random.......

Walking into work today, I saw not one, but two, pairs of abandoned women's shoes. How does this happen? They weren't terribly old or ruined shoes. They were just left in a random location - one in front of unemployment office and the other in a parking deck. Did their owner just walk out of them and continue on barefoot? Get carried away? Find a better pair? I expect to see the occasional single shoe on the side of the road. But a pair? Two pairs? Straaaaange.
