The teacher was discussing the math lesson then he suddenly called your name to answer the equation on the board but you were spacing out so you didn't know how to answer it. Samuel nudged your leg under the desks and low-key slid his notebook in front of your desk. His notebook has the answer for the equation so you said that answer and you were correct so you sat back down on your seat. Before you could have said thank you, Samuel already said "You're welcome" and took back his notebook.
