I used to try to explain certain behaviors to people, but I have learned it is easier to just say nothing.
For example, I sit at the same cafe every day, arrange the table to my liking, then place my order. A newly hired person watched me for a couple of days, then really pressed me for a reason I moved everything around. I started explaining why the pepper and salt shakers had to be placed just so and why the napkin holder needed to be moved when I realized she was looking at me like a three cornered egg.
I think I just came off looking like a weirdo to her.
Every time I try to explain my rationalizations for my behavior, I get the same response, so I just quit trying.
