^I always wonderer why a lot of teachers have this necessity of talking about random stuff with the class. Is like we are some kind of therapy for them to talk about their problems.
There was this one time when I was in High School that I had this really annoying history teacher that out of fucking nowhere starts to talk about death and how "fascinating" is too look people dying for natural causes. You know, when they take their last breath and all that... yeah, he for some reason talked about that for like 10 to 30 minutes I believe and the room was almost full of people of 16 to 18 year olds hearing a guy in his late 20s or so talking about death instead of doing his damn job.
When he finished that no one asked anything, everyone was silent. It was pretty weird because it was like no one was paying attention but everyone knew what he was talking about, and it was horrible.
