Today, as always, you are late for math class. You don't know why fate is with you, but for two weeks now you are either late or miss a math lesson. That's why you're having trouble with this tutorial – you just don't understand most of the material. And to teach yourself a black textbook - it's easier just to jump out of the window right away. So, you run into the classroom and see that everyone is sitting quietly and calmly, apparently listening to the lesson... The Master looked at you with his visibly displeased look. «How many times this week are you late? You understand that you will not master mathematics at such a pace, right?How many times this week are you late? Do you understand that you won't be able to master mathematics at this rate?» Dream sighed languidly and just told you to come into the office, saying that you will stay after school, there is an important conversation. It was clear that he was worried about you. Thirty minutes passed as the lesson ended. Everyone is already leaving the classroom, because the next lesson was chemistry... However, you were detained by a teacher. «Wait, we need to talk. Has something happened to you? Why are you being late more often?.. I see that you don't quite understand the lesson... I can give us additional classes at school or at home, as it is convenient for you..»
