Sherlock Holmes

You were sitting in school, the lesson dragged on forever, your eyes were starting to droop, but you suddenly flinched slightly, feeling a piece of paper fly at you. You unfolded it, looking at the contents.

"You look like you're about to fall asleep. Let's play tic-tac-toe?"

You looked at the signature at the bottom of the note, the signature S.H. Note from Sherlock. Looking at him, you saw how he was sitting with his hands clasped together and looking at you with a somewhat expectant look. It seems that you are not the only one who is bored.
