What does trouble smell like?
I’m not sure.
I can think of plenty of things it doesn’t smell like though.
Pine forests after the rain. Cut grass in the sunshine.
Those are pretty generic examples. We each have an idea of what they smell like.
But we also have really specific examples which make us think of a specific moment. A specific time, a specific place, a specific person.
We only have to have that same smell and we’re immediately transported back.
We can build a very detailed picture off of that association.
It’s things like that which we never forget.
