Why do teachers make high school sound so bad?

Why do teachers make it sound like hell?Note taking isn't as bad as they make it seem so why?I just started high school this year and it has been awesome so far it's like a repeat of grade 8 and it's great.I have semesters and 4 classes a day and 80 minutes per class but it's very rewarding.This semester I got some very lenient teachers and it's simply fabulous!
