I got a 2.
I answered "yes" to worrying about flooding, fire, etc. to the house, which sometimes runs through my mind in a "what if I came back to.." way when I'm gone for multiple days. And then answered "yes" to repeatedly checking lights, etc., which I always do before I leave the house for more than a day, but I chalk that up more to the early onset of Alzheimer's than to OCD. :)
