I do find untangling knots in yarn to be relaxing,
though.
It's pretty satisfying to solve a particularly nasty one.
I'll never understand how those knots form in the middle
of a very regularly-wound ball.
I have never understood how calbes seem to defy the laws of topology and
tie themselves into knots. But prectical experience shows that and set
of calbes left lying around will knot themselves together in a
ridiculously complicated way.
