My (PAST) Drama teacher's emails about a reahersal. I wont get a grade on this, and rehearsal alone will take 5 hours in all. 

I had Drama class last school quarter. I'm taking String Music now. Nobody in my grade nor the grade above me will get any grade for this. 

What is she gonna do if I don't show up? Give me an F?

She's not paying mind to ANY students' personal lives. One of my friend will have about 30 minutes to do their homework if they go to next practice.

I'm honestly just annoyed.
