When I was in first grade, I used to believe that the clear, flat marbles we used to decorate our vases with were contact lenses. I had seen my aunt wear contacts before, and I was convinced they were the same thing. In my classroom show-and-tell session, I showed the kids how many contact lenses I had. I was very offended when my teacher told me that I was mistaken.
