One thing I keep hearing as a bad thing is that multiple kids have attested to being invited to sleeping in his bedroom.
I just want to point out that his bedroom was the size of a normal middle class house.

I'm not weighing in one way or another, I just want to hilight that this anecdote on its own doesn't indicate anything beyond a sleepover.

But yeah, the heart of the matter is that we don't know, and never will know.
