I don't have classes, I don't have any reason to wake up before noon, unless you count homework, and I still can't sleep in.
This morning, I woke up at 7:40 a.m., but for some reason I thought it was 8:40 and decided that it was silly to try to go back to sleep. It wasn't until almost 40 minutes later that I realized my mistake. By then, I was completely awake with no hope of returning to dreamland.
Perhaps this will all change when I no longer have projects to do and papers to write, but I live in fear that I'm turning into an old woman who wants to sleep more than four hours a night but can't.
