Billy was three years old．One day,when he was trying to carry a bottle of milk from the table,he dropped it．There was a sea of milk all over the kitchen floor at once．
His mother came in．Instead of shouting at him,she said,"Billy,what a great and wonderful mess you have made!Would you like to play in the milk for a few minutes before we clean it up?"
He did．After a while,his mother said,"You know,Billy,whenever you make a mess like this,finally you have to clean it up．So,how would you like to do that?We could use paper,a towel or a mop．Which do you want to use?"
Billy used the paper and together they cleaned UP the milk．His mother then said,"Let's go out and fill the bottle with water in the yard． Let's see if you can find a right way to carry it without dropping it．"
It was at that moment that Billy knew he didn't need to be afraid of making mistakes．Instead he knew that mistakes were just opportunities for learning something new．
