I often see, whilst out walking, the odd small shoe, mitten, or anything else that can be dropped from a buggy. Inevitably someone will pick it up and position it prominently. I saw this shoe on my way to the shop; it was at the side of the pavement. Within the short time of my return it was placed thus, someone's front garden wall. I wonder if the parent will retrace his/her steps in order to find it?
