Oh well, the missing pebble still hasn't turned up. It has really driven me quite mad, I keep wandering distractedly around the house looking for it, and in the mean-time nothing much is getting done.
This pebble was of exceptional beauty and it had 'called out' to me on that day from beside the waterfall.
I felt it was a little like Faith's angel cards; each pebble has its own spirit, something which carries meaning and lends the day identity.
This one was going to help me with my painting with its personality and colours. It clearly decided not to!
I will just have to wait until it chooses to reveal itself to me again.

The trouble is, how can I return it to its resting place beside the waterfall if I can't find it.
