You cannot, in the end, accurately assume much about anyone.
Sexuality.
Intelligence.
Love.
Discipline.
Joy.
Grief.
So you play this game where you assume people’s reactions are basically the same, even though they’re so not. Most people, we really don’t have any idea who they are, or what they’re going to do. Some people, yes; but most people, no.
Stories are about people, but people are too complex to pin down to mere words. So all stories are inherently at least somewhat fiction, even the ones that we intend to be non-fiction.
Nuance is everything.
Be skeptical.
