Well, I can't say that I'm not a LITTLE nervous when our door bell rings and we aren't expecting someone. I shouldnt' worry, because my husband is DF'd now, and I'm sure we are thought of as a waste of time.
However, after 6 months or so of trying to avoid and hide from the elders, my initial reaction when the door bell rings, is that THEY'RE BACK!!!
One weekend we had an elder call us ( we didn't answer) he stopped over 3 minutes later and rang the door bell ( we didn't answer) then left and called again to leave a message saying he left KM's in our car since we weren't home.
