When I was a pioneer, we went to work unassigned territory in South Dakota. It was miserable at best. 30+ miles between houses/shacks, heat, bugs, all that.
I did have two "good" experiences that humbled me as a JW and opened my eyes. I went home a different person.
#1. Being a red-head and a woman, people at the doors wouldn't look me in the eye. One told me that the Devil/bad spirit is in redheads (got that right) and that it was disrespectful for me to assume they would want spiritual guidance from one. They would look at the "brother" I was with while I spoke.
#2. A VERY large man opened one door with no shirt on. He stopped me before I started and told me he would listen to me if I agreed to listen to him. I did my Watchtower ditty and then he asked if I was done. He went and got a peace pipe. It had rags tied down from it for at least 5 feet. In the rag were knots with 'leather' in the knots. He told me this was the skin of his ancestors. He showed me the scars on his chest and shoulders (which I had noticed) and told me that was where they hung him by hooks and when they cut him free, his skin went on the family peace pipe. Well, I was humbled....and he had taken time to speak to a red-headed woman too.
After that day, selling Watchtowers was a little less of a spiritual experience and a lot more like peddling s*&t.
