It took my breath away, that evening. If you’ve ever dreamed that you walked into your best-loved book or film or TV program, then maybe you’ve got some idea how it felt: things coming alive around you, strange and new and utterly familiar at the same time; the catch in your heartbeat as you move through the rooms that had such a vivid untouchable life in your mind, as your feet actually touch the carpet, as you breathe the air; the odd, secret glow of warmth as these people you’ve been watching for so long, from so far away, open their circle and sweep you into it.
