I think the easiest way a householder can ruin my day is for them to ask questions. They never seem to run out of them, and it seems to be leading to a study. For those calls to run on an hour or more is torture. And it's worse if the call happens when I am close to time to quit or we are almost out of things to do and the day is going to get cut short. That ruins my day when a call runs on killing my hope of a shortened day in service. Worse than rude householders. Worse than dogs. Worse than doors slammed in the face.
WTWizard: You better not call on me then because I try and never let the Witnesses leave in under 2 hours. My record is 4 1/2 hours. Of course, I try and make it as pleasant as possible with yum yums, but when they start to look comfortable, then I pull out the really tough questions! And like that young woman, we enjoy keeping the Witnesses from spreading their poison in our neighbourhood.
