I loved reading this story to my kids because it helps teach why it is so wrong to lie.
Brother and Sister Bear are bored and end up playing with a soccer ball in the tree house. Brother kicks the ball, Sister blocks it with her knee, and it smashes into a lamp on the side table. Mother Bear comes home from the store, Father Bear comes in, and the children tell a lie about a bird coming in and knocking it over. Father Bear notices the soccer ball underneath a chair. I won't ruin the ending, but my kids definately learned about how lies hurt people and hurt the person who lies in the process.
This book was printed in 1983, and still in great condition. It isn't exactly looking brand new, but for it's age it's in excellent shape.
