It was a cold December, and Mrs. Bell wanted to do a lot of shopping. She waited until it was Saturday, when her husband was free, and she took him to the shops with her to pay for everything and to carry for her what she had bought. They went to a lot of shops, and Mrs. Bell bought everything she could think of.

She often stopped and said, “Look, Peter! Isn’t that beautiful?”

“All right, my dear. How much is it?” answered Mr. Bell, and then he took money out to buy it for her.
