AGuest, thanks for pointing that out to me.
Quendi, I've always felt the same way as you, regarding being alert for clues about the householder and to listen. Years ago there was an Awake on Birth Control, which a young publisher proceeded to present to a householder in her 80's. Another time, an elderly householder said he was in pain, had health problems, poor eyesight and so on. The elder simply told him that everyone has problems, we can't sit around dwelling on them but instead we need to fill our minds with the positive upbuilding articles in these magazines....
And what about the times we'd go to a door and realize the householder (or return visit) had company? Or were in the middle of eating a meal? I'd always quickly acknowledge I came at a bad time and then I'd leave. Other publishers would go on and on with a lenghty presentation and even tell the householder to share the message with their visitors.
We can add to the list the householders who obviously had been sleeping. Some publishers wouldn't care. While walking away from the door they'd even be saying things to each other - which the householder can hear - accusing the householder of staying out late drinking and partying. How do they know what the householder was doing? Maybe they're working two jobs to pay off hospital bills. Maybe they were up all night taking care of an ill loved one. Or maybe they just want to sleep in. Who knows? No explanation is needed. Deal with things as you can see they are.
