The last time I saw my father ('10) I noticed that whenever I would talk to him he'd

-Maintain eye contact for less than 5 seconds.
-Have this routine that had to be the exact same thing every day. If something happened, then he acted like the whole day was shot.
-He's obsessed (I mean to the point where it's unbearable) with his gardens and maintaining them in a distinct way (He wouldn't let me pick any of the vegetables. He barely let me mow the 9 acre lawn, let alone aerate it.)
-He acts kind of like an asshole(Not saying ALL AS sufferers are.) and is kind of arrogant.

My stepmother on the other hand has full blown OCD, it's just that she hasn't been dx'ed.
