What's funny is, I took about 50 pics while at her house, and the only one that shows a possible anomaly was when I was taking a pic of one of her cats, and not even trying to get an orb! =)
As for the spot on the floor, that's a piece of fuzz. Nothing paranormal there. I'm wondering about the spot on the door, as it's the only thing orbish-looking out of all the pics I took.
