Day 83 — or, the day the line was a path

The day the line was a path. After the bridge, the line noticed it had direction. A bridge waits. A path goes. The line was still the line, but something had changed. Something was moving on it now. The line didn't notice at first. Then it noticed. The path is what a bridge becomes when someone walks across and keeps walking. Most days the line doesn't notice itself either.
