We’d already reached Fife by the time that I summoned up the courage to admit to JK that I’d forgotten to pack any socks to wear with my wellies. “Well, I suppose I could buy some in Braemar?” I suggested. “That assumes that we’re salmon fishing on the Dee today” she crossly replied, “but I was actually thinking of the Tay”.

She suddenly applied the brakes as we hit a rural traffic jam. Hundreds of children were crossing the road to a field full of cute brown cattle and tiny horses. I begged to join them, camera at the ready.

The children were strangely quiet. Soon I worked out why. They were deaf mutes on a special trip to study disability in the animal kingdom. The cattle, lacking eye sockets, were blind, and all the horses were without ears.
