It's better when that sort of thing happens at 3:05 pm in front of the elementary where one is a teacher, next to a school bus full of kids from that school, while attempting to trackstand on a fixed gear when one doesn't really know how to trackstand.
Yes, I did indeed children laughing. And yes, I did launch an investigation to find out exactly who those kids were. The invesigation was unsuccessful. I think some were my own students.
But I have since learned to trackstand.
