Not Quite What Gresley Had In Mind

My uncle messages me asking how we’re coping with lockdown.

Me: “We’re okay but [My Son] keeps asking me to take him to see the dinosaurs on the train.”

Uncle: “I presume that’s some sort of funfair ride he likes?”

Me: “No, the Natural History Museum. We go there on the train.”

Uncle: “Oh, I see. You mean that he wants you to take him, on the train, to see the dinosaurs. Sorry, I had a vision of the Flying Scotsman piloted by a stegosaur.”
