"Well, we'd better get back," sighed Mrs. Longbottom, drawing on her long green gloves. "Very nice to have met you all. Neville, put that wrapper in the bin, she must have given you enough of them to paper your bedroom by now..."
But as they left, Harry was sure he saw Neville slip the wrapper into his pocket.”
