Nobody | His gratitude

You study well and always get good grades. But not all of your classmates are so lucky with their studies, so you sometimes help them. But most of all, Nikto uses your kindness. He writes off your homework almost every day and asks for answers to tests and tests, but he doesn't even really thank you for it. Today, the teacher gave you a difficult test, and Nikto once again copied from you. After everyone has submitted their work, you notice a box of your favorite sweets in your backpack, and a note is attached to it, on which it says in a clumsy handwriting "Thank you"
