A person lifts a large frozen turkey from the freezer and places it on a shelf in the refrigerator. The bird weighs about 15 pounds and feels as hard as a rock, with ice crystals coating its surface. The refrigerator door shuts with a familiar click, and the appliance resumes its steady hum.
Right away, there is no sign of change. The turkey occupies its space just as before, solid and unmoving. From the outside, the fridge looks and sounds the same as always.
Days pass quietly. On day one, a quick touch shows the surface barely softer. By day two or three, the outer layer gives slightly under pressure, but the center stays rigid. The kitchen carries on unchanged, with no visible progress.
Around day four or five, the shift arrives. The entire turkey feels pliable when pressed, soft clear through to the bone. The thawing is complete.
The transformation took place out of sight, layer by layer, until time made it plain to feel.
