In which Ronni learns the same lesson all over again

I woke up today feeling mopey and defeated. This is not an uncommon occurrence, especially recently. For no particular reason at all, I'll wake up and feel so crushed, so hopeless, so unable to cope with (unspecified) stuff that it's an effort even to open my eyes. I had no desire to eat, no desire to do a single thing. What got me out of bed, in fact, was the need to do laundry and the fear that if I left it too late, the two washing machines would be taken. (Yes, in a fit of brilliance, the designers of this block of student flats provided only two washing machines for more than 100 students.)

Most importantly, I had no desire to interact with another human being.

Try as I might, the feeling didn't leave me for the entire day. At least, not until after I went to my language class and talked to people and did exercises about German geography and just generally partook in human interaction.

Why do I never learn? The days I feel least like talking to other human beings are the days I require it the most.
