In this line of thought are people that seem to naturally gravitate to the smallest pathways, hang around at the top of escalators/inside doorways, or are looking at the ceiling as they wheel around grocery stores. I guarantee that if there is a display in the middle of an aisle, someone will park their cart right next to it so that no one can get through. I have my children on the lookout for it. I have thought about taking pictures and starting a website devoted to the lack of brain cells in today's society-featuring shopping cart placement, inopportune gathering places, and those that walk around with their eyes cast skyward. I think that it goes without saying that there could be a whole site devoted to people that think they can talk on their cell phones and function.
