Bathroom Thought

Does choosing to work from the dark to the light say something about my personality?

Yesterday afternoon at work, I needed to use the restroom, as does any good citizen who over-consumes the coffee. As I open the door to restroom, the cleaning lady is in there cleaning the toilets. Trying to be nice, I ask her which ones she has already cleaned. She tells me it doesn’t matter. Now, this bathroom has one side of the 5 stall line that is significantly darker than the other side of the room. I just assumed that she started at the darker end and worked her way up to the light-filled end. So I chose the stall on the darker side just next to the one she was cleaning. Lo and behold, her next stop is the darkest stall.
For some odd reason, it hit me as an aspect of my personality that it says something about my assumption. For me to think that one should work from darker side to lighter side struck me as a need to work hard to get from the darker side (evil) to the lighter side (good). Where did this come from? I have no clue, but it was an interesting insight into my mind. Overanalyzing? Probably. But I thought what I thought and I thought I should share.
