DaCheech there was a story maybe in a literature? or in a public talk? that went like this: two sisters (tm) were witnessing in a nice residential area. After telling the reason of the visit at the intercom the house owner didn't let them in. So as the sisters proceeded going away, one mentioned to an other: I think I'll keep this house for myself. This was heard over the intercom, so the house owner rushed to the door: what, what? what do you mean? And as the story goes, they started a study with him, because he wanted to know how he can keep his beautiful house.
Now I don't know how much of this is true, but I find it strange - as Farkel put it right in his "Field Service Presentations That Tell the Truth", if I were in that situation I'd rather get my shotgun that to start a study with someone who's dreaming of moving into my house.
