Getting a mere seven hours of sleep is okay on occasion but it's not enough for me over the long haul. If fact, I often feel I'm more an eight and half-hour guy.
When one has really had enough sleep, I think a person wakes up before the alarm. It can even become uncanny when one's eyes automatically pop open a few minutes before the noise starts.
Anyway, the discussion is of no concern for a while. It's not important for quite a while. My class completed their final examinations today. The levels I teach are not even offered during August this year. That is a forced break. After that comes my voluntary vacation. We're leaving for Rome in mid-September, so I will not be able to start classes that begin that month. It's possible I might not even be in a classroom until the latter part of October.
I have nearly three months of complete freedom from my dreaded, screaming alarm clock.
