John
It happened in the library. We had to be quiet. We agreed to meet and study for the final exam amidst the reference books and all. Stacey sat down and flipped her hair back. I sat still arriving first, choosing the table at the back. Harold was serious about the study. He walked in slowly. Harold sat near Stacey and began to point out the highlights of osmosis in liquids. There were books about osmosis in non-liquid form as well.
We had books and notes all over the place. We were getting into it scientifically and philosophically, keeping the noise level down.
Then it happened. "John" walked out of the bookshelf. We could see through him. He sat and whispered, "Osmosis. Pass through a membrane. Go where there is more on the other side."
Everyone left in a hurry. No one knew John.
