I never was comfortable with it, even though I regular pioneered for a decade.
A slight highjack of this thread.....
Last week our doorbell rang during dinner and Bobby answered the door and told them we were having dinner. The women said they would come back and he said "Please do not". About an hour later the door bell rings again, by this time I am in my PJ's and Bobby is in bed, now the dog starts barking like crazy. I open the door and one of my cats runs out (and it was below zero at the time). I thought they must be nuts to be out knocking on doors in below zero weather. They were trying to sell internet service or something of the kind and I was really pissed. The heat and cats were escaping out the open door, the dog is waking up everyone in the house and they are trying to sell me something lame. I wondered what in the hell would possess people to do this.
It made me wonder how many people I did this to people through the years.
