I think the first thing I think of, has to be why on earth someone would either tear off a key, or just leave the next computer user with such a disgrace. Second of all, where has this key now vanished to? If it has not been put back, where is this missing key?
Next, I think I go into a state of self pity, which isn't really a good state to be in. Keyboard keys not not only quickly frustrate someone-but begin to make one think that maybe this is more than just a coincidence. Did I do something to deserve a missing key? Why me? Why was I chosen today to face this challenging circumstance? Quickly a mere key situation has resulted in serious life questions.
