At the end of the primary school term, a kindergarten teacher is receiving gifts from her departing pupils. First up is the local florist's son, whose gift is a well-wrapped cone.
"I bet I know what it is," she says, after shaking it and inhaling deeply. "Have you got me flowers?"
"That's right!" cries the boy. "But how did you know?"
"Just a wild guess," she said, grinning.
The next pupil was the daughter of the local sweetshop owner. Again, the teacher held her box over her head, shook it, and heard the soft rattle.
"Thank you," she says, "I love chocolates!"
"That's right! But how did you know?" asked the girl.
"Just a lucky guess," laughs the teacher.
Finally, the son of the local off-licence owner shyly approaches. Again, the teacher holds his box above her head and shakes it side to side - only to find it leaking.
"Mmmm," she says, tasting a drop of the leakage with her finger. "Is it wine?"
Open-mouthed, the youngster shakes his head - and the teacher repeats the process.
"Oh. Is it a nice vintage champagne, perhaps?" she asks.
Again, the boy shakes his head excitedly.
"OK," admits the teacher, "I give up. What is it?"
The boy laughs in delight. "A puppy!"
