Seldom, very seldom, does complete truth belong to any human disclosure; seldom can it happen that something is not a little disguised, or a little mistaken.
— Jane Austen ‧ Emma

Our reading
An editorial interpretation.
The line is gently sceptical about how much people ever tell each other straight. Even sincere disclosures pick up a little disguise or a little error along the way. 'Seldom, very seldom' repeats itself like a patient shake of the head, wary of tidy stories without being cynical.
