[Quiet Man Cometh]

I get obsessed with symmetry sometimes, like if I step on a division between sidewalk slabs with one foot, I must then do it with other foot or the difference in sensation between my feet bothers me. I grew out of it for the most part, I think. A lot of members in my family display OCD behavior to varying degrees, but I think it's only been a real problem in a couple of cases.

I wonder if some if it wasn't childhood exposure. My mom likes to arranged things in tidy, symmetrical piles, like a stack of magazines being perfectly aligned and square, but not the rest of the items on the table. My brother and I do it too, like we might have picked it up by observation as kids. My sister in law likes to poke the little 'arrangements' and see how long it takes one of us to come by and fix it.
