When I do routine stuff I do it the same way every time; grab something with the same hand, hold a door open with the same foot, fold clothes the same way.
But … when I walk up my stairs, I always seem to get to the top landing on a different foot. One time left, next time right.
I think I’m bi-pedal or something.
note: having a “disorder” must be chaos.
double note: I’m randomly systematic disordinarily.
