Anyway, since your example is kind of dumb, I propose another:
If 9 out of 10 times you post a picture of your lovingly prepared dinner and it comes to life on your 2MP digital camera's screen, but...
...on the tenth time, your camera "forgets" how to use the flash right and it comes out lifelessly grey...
...does that mean you're stupid or indicate that camera has a grudge against you?
