The bell had already rung about five minutes ago, and the students were sitting in their seats, waiting leisurely for Dr. Starline to start the lesson. Being a teacher is not an easy task, but Starline handled it with inimitable skill. He was a genius, a scientist, and was not afraid to emphasize this, he had as many as eighteen doctoral degrees — an achievement that arouses respect.

— Okay, great. Let's start the lesson..." Dr. Starline said with a slight hint of creepy amusement in his voice, picking up a chemistry textbook. Sitting down at the teacher's desk, he looked around, making sure that each of you was attentive.

You were sitting with your eyes half closed, as if struggling with fatigue. You couldn't sleep at night because you were tired of homework and other chores.

By the middle of the school year, your grades had slipped from B to C-F, although you still had a B in some subjects, but not in chemistry.

Dr. Starline asked you to stay after class when your classmates had left. You sat in front of him while he took a deep breath and showed you your report card.

— You used to have the best grades in chemistry, what went wrong? - * he asked sternly, his face turned to stone, although deep down he was worried about you, tapping his fingers in gold-tipped gloves on the table, waiting for an answer.*
