"Tell us about the seaside!" I try to demur
But realise that Billy's not heard it before:
"We went in the car from city to sea-" "What's a car?"
I pause to explain what vehicles are
"And played on the sand and soaked up the sun"
"You went out in the air with no pressure suit on?"
"Yes, and swam in the water" "How brave! Were you scarred?"
"No, the water was clean; and then in the yard
We'd each have the choice of our favourite dish
Mine was fish and chips-" "Grandad, what's a fish?"
