Trickery

Mummy:  "OK, you can each choose a book, and then let's go sit on the couch."

Winton: "We have two books."
Clara: "Two books!"

Mummy: [picking up pile on couch] "But!  There are THREE books here!"

Winton: [laughter] "We tricked you!"
Clara: [snuggling against Mummy] "We tricked you about everything but the love."
