I have decided my own computer has a borderline personality, with tendencies both narcissistic and histrionic - it has random bouts of crazy hostility with generally irrational behavior, acting out, bizarre reactions to simple requests, unpredictable moping, etc. Just like one of my old girl friends, actually. For example, this morning, it refused to put any icons on the desktop. And it's been dropping graphics from websites, for no discernible reason. Then it slows to a crawl for an hour at a time, or freezes between toggles, and sneers at me, "I dare you to reboot me - I dare you!"
I have become (like everybody else) entirely dependent on the little suckers - but I hate them.
