“She did not seem to want to speak, or perhaps she was not able to, but she made timid motions toward Neville, holding something in her outstretched hand.
“Again?” said Mrs. Longbottom, sounding slightly weary. “Very well, Alice dear, very well- Neville, take it, whatever it is…”
But Neville had already stretched out his hand, into which his mother dropped an empty Droobles Blowing Gum wrapper.
“Very nice, dear,” said Neville’s grandmother in a falsely cheery voice, patting his mother on the shoulder. But Neville said quietly, “Thanks Mum.”
His mother tottered away, back up the ward, humming to herself. Neville looked around at the others, his expression defiant, as though daring them to laugh, but Harry did not think he’d ever found anything less funny in his life.
“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.”
