I agree. It seems like people sometimes look at me and they see a thread that they just have to pull, especially after they are around me for a while.
I think they know we are different somehow, but can't put their finger on it. They spend their lives trying to fit in, and can't understand why someone would do something that is to them so obviously not "normal."
It's funny you should mention this, I'll be interested to hear if a lot of people get asked these sort of pointless questions. Maybe it should be a "symptom"
I just remembered, the other day I was out painting on the side of the road, with an easel..... and a paintbrush in my hand, and this hick drove up and asked me, "what are you Doing?"
