A teacher was in a class with around thirty little kids.  "OK everybody" she said. "I'm going to hold something behind my back and describe it to you, and I want you to guess what it is."  And so she starts to describe the first item.  "It's round, red in colour, and fairly small" she says.  One of the children calls out "Is it a tomato?"

"No" replies the teacher.  "But I like your answer. It shows that you were thinking.  It's actually a cherry."

The teacher starts again.  "It's round, orange in colour..."  One of the kids suddenly butts in "It's an orange!"

"No" replies the teacher.  "Good answer though, it shows that you were thinking.  It's a satsuma."  And so the teacher starts again.

"I'm holding a rectangular object, white in colour, and very soft."  One of the kids asks "Is it a piece of white chocolate?"

"No" replies the teacher.  "But you came up with a good answer.  It shows that you were thinking.  It's actually an eraser."

Suddenly a kid at the back of the class puts his hand up.  "Yes Wille?" enquires the teacher.

"Can I play the game as well but do the describing bit?" asks Willie.

The teacher considers the request for a minute and then says "OK, go on then."  And with that Willie gets up from hiis chair, walks to the back of the classroom, faces the wall and, after a bit of fidgeting for a few seconds, says, "Im holding something about two inches long, with a red tip on the end..."

"Willie!" the teacher calls out loudly.

"No" says Willie.  "But I like your answer.  It shows that you were thinking.  It's a match."
