On another note, today as I was doing some gardening I heard what sounded like at least two people, so I did my usual thing and hid behind the hedges while they passed. As I was hiding the noise got closer but there was only one set of footsteps. So it turned out that it had only been one woman singing to herself. It made me chuckle and then I carried on chopping the hedges. Now I have a shaky hand because my muscles have gone into shock. I like gardening.
