Drawing a car in public

While waiting on DH's car to have the oil changed and be detailed I sat outside the waiting room and drew. I decided when I got home to add a little color with watercolor pencils (this paper is not designed for any wet medium). No one seem to find it strange at all, one guy actually told me it was a great way to pass the time. He and I then proceeded to have a discussion on drawing and our favorite artists. So many people talk about drawing in public with fear and trembling, I have never really had any problem drawing around absolute strangers. I am much more afraid to draw around people that I know or will see again. (oh well, my daughters do tell me I am a bit strange)
