1. A wagtail chasing something across the roof outside the office.
2. Walking with someone who has a sense of direction. I navigate by landmarks and always want to know exactly where I am on the map. I went for a stroll with Douglas at lunchtime and because he always knows where he is in relation to things like roads and witch's towers, we ended up wandering off the path and into the woods.
3. Walking up the high street on my way home when the air is heavy with water and full of good smells.
