I dunno how, but I usually find myself behind the slowest person on the stairs.  If there’s people who look perfectly normal, they will walk very very slowly ahead of me.  Baby carriages mysteriously appear above.  Canes I did not notice are up in force.

This morning, I thought I’d beat the system because I was in the exact center of two people, so I would pull away to whichever side moved faster.

Neither was.

Point, stairs.
