After a month cooped up in a Scottish castle, no internet, no TV, and no radio, watching hectic snowflakes billowing through the wooded hillside opposite my window, I realise that what I’ve missed most about this supposed deprivation has not been the news (to which I thought I was addicted) or the chatter, the company of other voices, but the chance to be taken in my head to other places and inside quite different experiences of life.
