@forteller Ha… I just dropped off my own kid and cycled away on a unicycle (but not in Tøyen! 😉 ).
I can't speak for this other guy but my child and I came by bus and then after that I cycled on to work.
However I have another theory for this person. I know a couple of dads in Oslo whose children unicycle *very* well. Perhaps the kid came on a unicycle as well?
Tomorrow look at the locked up kids "bikes", perhaps one of them is "missing a wheel". 😜
