When I went grocery shopping the other day I saw a penny on the ground, and I had an overwhelming urge to pick it up in spite of the fact that I was carrying three bags of groceries. When I was a small child, my arms were usually swinging at my sides. I would pick up a penny if I saw one, look around, and discretely shove it in my mouth before anyone caught me. Oh how delicious. After I look back at all of the weird things I ate as a kid, I’m glad I had my tetanus shots.
