Sitting quietly in his buggy, Joe suddenly pointed to the sky and excitedly shouted “A plane!”. We all looked up. Streaking across the sky above us was a long vapour trail and a plane shining bright in the sun at the head of it.
“Wow!”, said one of our friends. “Where do you think it is flying to?”
Joe gave it a second of thought.
“Er, the airport.”
We all had to agree he was probably right.
