I show up for an appointment to do some repairs, and the woman tenant is old and frail. I mean really, really old!
She is underfoot while I'm trying to evaluate the repair, so to get her out of the way, I lead her to the closest chair and have her sit down.
I tell her I'll come to her if I have questions. In short order, I determine the problem and find that I need to go to the hardware store for materials. I tell the old woman I have to go to the store and ask her if she has to be somewhere else before I can return in about 45 minutes. Still sitting in the chair, she says, "No." I say, "Okay, wait right here and I'll be back as soon as possible." When I returned, I knocked on the door and waited. And waited....and knocked....and waited. Finally, I partially open the front door and yell, "I'm back!" I hear some muted response, and as I enter, I see the old woman who immediately says to me, "I didn't move from the chair. I stayed right where you told me to stay."
That's not what I meant!
As I'm doing the repair, I wondered how long she would have sat there had I not returned.
