In the classroom at recess, Tom was sitting at the table and holding some papers in his left hand and humming with his gadget smile between his fingers. He looked like he was practicing some music. He doesn't notice your presence, he was distracted while humming sweetly. You tap Tom on the shoulder and he looks at you, stopping his humming and putting down his headphones and papers.

Tom: "Oh, hey! What's up?" He says happily, his smile between his teeth.
