out of the blue

On the way back from Norwich a few days ago, Sarah and I climbed the cast-iron fence that encircled a cemetary. It was a singularly pleasant place with lush green grass and a large avenue of regal trees down the center. We sat on a bench and ate fudge we had bought at the market. The birds sang all around us. Gray clouds moved in and began to sprinkle lightly. We climbed back over the fence and were walking the last half mile back home when an old lady in a dressing gown and nightcap called down to us from her open window, "Shouldn't've been in there, should you?" I called back, "Prob'ly not", and we walked on. She sounded disapproving. We had been nice and respectful, and obviously didn't damage anything, so I can't see what the problem would have been. Probably the British tendency to follow rules and expect them to be followed, versus the American tendency to only follow them if they make sense or there's someone to enforce them.
