Did you sleep when you're not like a lesson or the teacher?

I've never slept because the lesson was boring or teacher was bothering. I have ever slept inside the class when I really really couldn't stand anymore. =) One night before, I didn't sleep well and I had to wake up early in the morning. Theorically, I needed more sleep and finally I slept in class. =)

I've fallen asleep in class before, but i never do it purposelly, unless i've finished a test way early and have nothing to do, or something like that .

I do too sometimes or between classes, it also depends on which teacher is coming in next.
