[Canaletto]

I found it bizarre that the 20-somethings and 30-somethings seemed to be carrying on a conversation, while the 40-somethings seemed to be throwing out random comments that had little or nothing to do with one another.

You mean like suddenly saying "I don't know what it is, but I can't sit in the house naked, even alone. It doesn't feel right."?

Yeah, they did seem to be a bit random.
