My neighbour who has lived in the same house for 18 years and is a keen gardener, was telling me just the other day how the sun is coming in at a different angle. The reason she knows this, is that her garden (which has been in the same location for all of those 18 years), no longer gets the sun in the same spots. Interesting I thought. This from a woman who is not a whoowhoo...and does not visit here.
