Is OCD hereditary?

 

I come in this evening to find my three year old son, Max with my wife’s cotton makeup removal pads (he calls them Fuzzies):

Nigel has many a time organized shoes, pencils, pens, etc.

While it is true that I am very particular about a lot of things, I don’t technically have OCD.  OCPD, maybe.

Maybe that is why I collect things like coins, pens, knives, watches, guns, rocks, bayonets, tools, etc.
