A Story About When I Was Young

When I was in first grade, I went to a school which had on the playground a huge tractor tire filled with dirt or something that kids could play in. One day, I hid in it after the bell rang, thinking that someone would notice I was missing and come looking for me. No one came. I walked back to my classroom feeling lonely and ashamed. This incident colored my whole life, and probably explains a lot. I'd appreciate if you didn't speculate as to what.
