I was looking at the latest missive from Royal Mail about the changes in post pricing.
"It comes into effect on 21st August - a special day," I remarked.
Keith immediately assumed that hunted look which indicates that the significance of this day is something he should remember but doesn't.
"Something I should know about?" he asked desperately clutching at straws.
"Oh yes," I said.
He screwed up his face and gazed at the ceiling in the hope that inspiration might yet strike.
"Catch-up day?" he suggested hopefully.
"Catch-up day?" I queried.
"The day you become the same age as me again."
"That's the one," I said.
