Diagonals

When I see an object, I often mentally draw lines, most often straight, between non-adjacent vertices of it. A table, a cup, a window, a car, the corners of a dog's head, the borders of a lush tree. The corners of someone's eyes, the nose bridge to the nose tip, the tip to the cheek ridge, the top of the lip to the side, the top of the ear to the bottom, the hair forefront to the back of the head. I imagine this helps me calculate the sizes and internal ratios of objects, although it is exaggerated to conscious proportions. I wonder if I can make it fully unconscious again.

This phenomenon constantly distracts me from whatever I'm doing, and introduces considerable overhead into my thoughts. I first noticed this behavior in high school, and I think I've only now expressed it at all.
