PROOF IF PROOF WERE NEEDED

Once, I went on a walk with my most beloved partner in crime. It was in the Welsh hills. We walked along, in companiionable silence.
Looking at the valley, I said, "Do you know what that reminds me of?"
"The 39 Steps?"
"How on EARTH did you guess that?"
I was gobsmacked. Our walk continued without further guessing games.
Later, in the same walk, towards evening, we looked across at a distant evening vista, hill upon misty hill.
"OK smartarse," I said, "you'll never guess what that reminds me of?"
"Narnia?"
"I don't bloody believe it!"
