Maybe it was her way of saying they didn't fit in. "We live in a bedroom community, but we're really more of a garage family."
Sorry : /
In a vaguely relevent defense of the VDs, I think in the past there was lots of speculation about their income. We now know that they have made money on the side for years in real estate. That's one reason she used that term.
Glad you said that. I didn't know they were making money on the side. That would explain some things. There are likely explanations for many of the things we find suspicious about the VD's and I would accept any of those explanations, UP and UNTIL Danielle's disappearance.
Then I say, doesn't matter , they had no reason from that point on to LIE to POLICE while their daughter could have been found alive. (unless they already knew she was dead, for instance).
