On the last day of school before Christmas break, children brought gifts for their teacher.

The supermarket manager's daughter brought the teacher a basket of assorted fruit. 

The florist's son brought the teacher a bouquet of flowers. 

The candy-store owner's daughter gave the teacher a pretty box of candy. 

Then the liquor-store owner's son brought up a big, heavy box. The teacher lifted it up and noticed it was leaking a little bit. She touched a drop of the liquid with her finger and tasted it. 

"Is it wine?" she guessed.

"No," the boy replied.
