It happens every time, they all become blueberries!

Our reading
An editorial interpretation.
An absurd, cheerfully offhand claim that people keep turning into blueberries, as though it's an everyday hazard. The humour comes from the casual tone, treating something bizarre as a predictable routine. It's fantasy nonsense delivered with the confidence of someone who has seen it before.
