We had a couple of rescue cats a few years back, Rollo and Ripley. Rollo was just formidable in his enjoyment of life, Ripley was so shy, he hardly ever came near us.
One night, I couldn't sleep, so came downstairs to slouch on the sofa for either some sort of kip, or at least a chance to stretch out and let Mrs Growster sleep on. Ripley suddenly appeared, and as I was so quiet, he came up and just lay down next to me, and for the first time ever, I heard the softest purr you could even imagine!
Dear, dear boy...
