Hey, they all do!!
I have chamestry frst 2 hours (and we start at 7:30 am) so yeah....me knos how it is to sleep in class, and I don't even know why they get mad, cuz she always says:
"You can't sleep in my class, I won't allow it, chamestry is something that you do every day, for example when you wash your teath, tooth paste is all chamestry,...plus if you'll sleep you won't learn anything,..."
I mean wtf, gtfo!!! have As and 2 Bs in chamestry, it's really easy, so I dunno why she complains sooooo much, bitch!!!
