We could have done this anywhere with good wifi and a spare room. We chose the Highlands because the landscape does something to the mind that a city never will: it slows it down without asking.
There is no signal to chase out here, no reason to rush between two unremarkable obligations. The hills don't hurry. The weather arrives and leaves on its own schedule, and after a day or two you begin to keep its time instead of your phone's.
Quiet, it turns out, is not the absence of sound. It is the presence of enough space to hear your own thinking. Scotland has more of that than almost anywhere we know.
