It sounds like an old riddle: how many skinned knees does it take to teach a kid how to ride a bike? The answer is “too, too many” and it’s no joke, just bloody fact, as AIR MAIL Pilot well remembers, and you may, too.

So hats off (and teeth privately gnashed) to Daisy Adams, who lives in Bristol, England. She’s only four but can already ride a unicycle—the tricky, one-wheeled conveyance beloved by clowns, jugglers, and a certain type of kid with annoyingly whimsical affectations who you may meet in high school.
