Sadness was a different thing. It was heavy, and he could sometimes sense it around his mother, even when she was happy. He didn't know why she was sad, when she had him and father and Pansy and such a big house. He had asked Pansy once if she ever got sad, and she had said yes but when he asked her why his mummy was so sad sometimes, Pansy hadn't answered and instead found a new game for them to play.
