The same thing happens to me. I look down for a second and she changes direction. I guess that means I am confused.
You have a lot of company. ;)
If I stare at her for the 30 seconds, while she is spinning counterclockwise, which she usually is when I first look, she instantly changes directions and begins spinning clockwise after 15-16 seconds. So I suppose that means I’m a dominant right brain thinker.
