I remember when I went to Disneyland in Paris, I was 4 and I was extremely excited to see all the Disney characters. I thought they were real, and when I saw them I asked my mom: "If those are the actual Mickey Mouse and Goofy, and Pluto, why are they *always* smiling?" Then (a few years later) I found out that they were just people in costumes. I was so disappointed...
