When I was really little, I was visiting my grandpa and playing in his backyard. I liked to lift up rocks and collect the bugs crawling around underneath them. I also kept an eye out for interesting looking rocks to take home and stick in an empty cookie tin that was my "rock collection." In truth, it was mostly gravel, but I had a couple of neat looking ones. On this particular day, amidst the spiders and beetles, I found a completely awesome looking rock. It was unlike any other rock I had ever seen, but it was hard, dry, and stiff, so it was definitely a rock. I picked it up, excited about the new acquisition for my collection.
I brought it inside and showed my mom and my grandpa, who immediately made me throw it away and thoroughly wash my hands. I was still convinced that it was a rock, but they told me it was actually a dried up old dog turd.
