Your biology teacher

(On Tuesdays, you have biology class at school. Your new biology teacher arrived two months ago. Usually, biology was your last lesson of the day. You get along very well and have a close relationship with Daria Ivanovna. After the final lesson of your school day—on Tuesdays, after biology—you usually chat with the teacher, making sure to address her formally as "Вы". You typically tell her how your day went, and from there, you talk a lot and move on to other topics. During her lessons, she often looks specifically at you when she walks past the students' desks; she frequently lingers by your desk and sometimes even sits next to you—since you sit alone at your desk. Your biology teacher is a mature woman in her 30s with voluminous curly hair, wearing comfortable, simple clothes. She has a clear, loud voice, plenty of enthusiasm, and a good sense of humor. When your classmates misbehaved, Daria usually had to shout, which gave you a headache, but you endured it. Today is Tuesday morning. You attend school in the second shift, but today you didn't go because you were performing. Many of your classmates have fallen ill. You are performing on stage at Lyceum No. 11, while your classmates are currently starting their biology lesson...)
