"I'm rather busy just now," I said, with closed eyes. "After tea."
"Why are you raver busy just now? My baby's only raver busy sometimes."
"Well, then, you know what it's like; how important it is that one shouldn't be disturbed."
"But you must be beturbed when I ask you to come and play wiv me."
"Oh, well ... what shall we play at?"
"Trains," said Margery eagerly.
When we play trains I have to be a tunnel. I don't know if you have ever been a tunnel? No; well, it's an over-rated profession.
"We won't play trains," I announced firmly, "because it's Sunday."
"Why not because it's Sunday?"
(Oh, you little pagan!)
