We are promised by our teacher that we can watch movie during the self-learning period of this evening. At 7.20 we started to watch the movie, but one minute later the vice-headmaster who is a horribly conservative guy forced us, as well as several other classes, to stop.

I never attend the self-learning in the evening.
