to ski or not to ski, that is the question

sidewalks and artificial constraints

(yet another post in the funny how serious)

seems like i strive to contrive, take long strides, go out of step etc. to make sure that the start or end step coincides with the line between two stones/slabs.
is it just me, or does everyone like to synchronize their footsteps with the start/end of the sidewalk stones/slabs?

as an side, this reminded me that most constraints are artificial. no real reason to do what i do :-)
