We have a graduated scale of visitor tolerance:
People carrying copies of Watchtower: 0 seconds.
Grand Children visiting as a pack: 1 hour.
Single Grand Children: 2 hours.
Friends who need entertaining and who constantly need to 'do stuff: 1-2 nights.
Friends who just want to chill/doss and don't need constant tlc: 3-4 nights.
I just don't answer my front door, friends know to call, solves the Jehovite/Mormon/Baptist problem nicely, along with my being at work 10+ hours per day, and Mrs. GA working as well. I once was approached in the garage by some Mormons, but they just wondered if I could fix one of their very nice bicycles. It was well with them, because they did not try to convert me to Mormonism. I can't see the appropriateness in walking up to someone you don't know, and telling them their present relationship with the
Diety as all horsepoo, even though you don't know them, and that your religion is a better model for them to follow.
