There was only 1/2 an hour left at school when Sammy came walking into the office and saw me there and she said he caught you too then and I just nodd...ed at her. Sammy then sat down beside me and we both waited until our teacher came in. He had a strange look in his eyes that both me and Sammy noticed and were not sure on. He told us to get up and follow him to 2 class rooms and the far end of the school that did not get used much and he took me into one and Sammy into another and told us to sit.

What does yours say?”I read the markings on the side. “It says ‘Diff’. Difference, maybe? Even though I can’t see a difference.”“I think it might be diffusion.”“Hmm. All.
