One day, a little girl went into her father's study, looking for her dad. She saw him at his work.

"Daddy, are you free to play with me?"

"Oh, not now, darling. I am very busy right now."

"Oh. Is there anything I can help you with then?"

So her dad asked her to help him fetch a particular book from another room, very far away from his study. Ecstatic, the little girl raced off to the other room, and a few minutes later, came back happily panting, handed him the book.

The father took a look at the book cover. It was the wrong one.

And the father bent down, embraced her with the biggest hug he could muster, and said, "Thank you so much, darling, for your help. You are my helpful little girl!" The little daughter happily kissed her dad and skipped out of the room.

The father then, without a word, quietly got up and went off to get the correct book.
