memoir: revise childhood transition section with more quotes

I suspect coach might condemn the word choices as cowardice (I'm
making these edits in response to feedback from someone on the other
side the issue), but the fact that I'm including more quotes (which
are realistic even if—if—they're hypothetical) just seems like a
Pareto improvement no matter what words I write around them.

(People on the other side will see nothing wrong with the quotes and
be glad that I'm citing evidence instead of confabulating assumptions
about events where I wasn't present; people who see things my way will
look at the dialogue and cry, "This is grooming!")
