I was always scared to walk over bridges, especially wooden ones. I thought that they would collapse on me (probably got this idea from watching too much disaster tv or something). One day, when I refused to walk over a bridge, my mom told me to walk across where the nails were, cause underneath the nails were the beams that held the bridge up, so if the bridge collapsed I would still be standing on the beams and be safe. This made perfect sense to me and I never had a problem again. I guess it never occured to me that the beams would probably fall too. The funny part is, I'm now 20 years old and I still find myself walking on the nails whenever I cross a wooden bridge. :)
