Yes, this exactly. A few times I have left myself logged in while I change clothes, or go grab takeout from the dining hall downstairs, or even take a quick shower. It's people who leave themselves idle for hours so that they don't have to try to log back in later that is frustrating. I understand where they are coming from, but it's hardly fair to the rest of us. I'm not doing it myself both because I feel it isn't fair, and because I don't want to put that kind of stress on my laptop. My last hard drive (less than a year old) bricked just a month ago and I had to replace it, so I'm especially cautious now about leaving it on when I'm not using it.
