... has anybody wondered where I've been for the last couple of days?

No matter whether you did or not, I'm back now to tell you exactly that - where I've been. At home. With a cold, I think. All I know is that I woke up on friday, feeling like I hadn't slept at all, but gone to school because of a German exam (when I probably should have stayed at home because I obviously was ill already by then), didn't do overly well in my exam. went home after the 3rd lesson because I was feeling more and more horrible... and spent the past 2 days mainly lying around on the couch coughing/doing nothing. I hate being ill, really.

aaanyways, now you know, and there is no (real) need to worry.
