Good morning, dreamer.
It's possible that the visit to your old middle school awakened feelings of nostalgia. In a new school, it often seems as if we don't fit in, and that's what the ant hill reminds me of - the bustle in the hallways of a high school, and the stings of the cliques that reject us. In such a situation, it's only natural to seek the comfort and safety of the familiar. I would hazard a guess that you don't have the same bond with the coach(es) in high school.
