I am a pro at sleeping in class. I have been caught many times but never got in trouble. The best way to do it if you teacher is mean put your elbow on the table an d rest your head on your hand with a book infront. Never got caugth doing that.
Times I have been caught. Once I was in sleepenomics and had fallen fast asleep. Well I started to have a dream that I was driving my dad cars and before I knew it there was a car coming at me, well I woke very quickly and when I opened my eyes everyone was looking at me (including the teacher), according to them I made a funny sound!
The best time I got caught was the day I had to hand in a large english project and I had stayed up all night with studying and finsihing this project. Well I handed it in 2nd period, and when the teacher was collecting them and looking at them I fell fast asleep again!! This time the period bell did not wake me up, and the teacher left me there for 2 class periods, and break he ended waking me up infront of his freshman class just before lunch! I really was not too embarressed he was really cool about, and I had a good sleep!!
The think you will not get in much trouble depending on how good you are. I was a very good student, good grades, always handed my work in on time, not really that polite in class (I was more of the class clown!) but I must of done something right as I never got in trouble!
