“These vehicles are horseless carriages.”
“How do you know that the carriages are horseless?” asked Alice.
“Because they haven’t got any real horses drawing them.”
“I didn’t know that real horses could draw. Can they also paint?”
“Alice! You must know what I mean!” Celia cried. “A horseless carriage is what the people of the future call a carriage that isn’t being pulled by a horse.”
“Is that similar to a pianoless lampshade?” asked Alice.
“Whatever’s a pianoless lampshade?” asked Celia.
“Why, it’s a lampshade that isn’t being played by a piano, of course.”
“Alice! I’m getting rather tired of your loopiness!” Celia replied.
