This stupid manager/analyst comes to my desk complaining that everything's stopped working. He was quite angry. I check it out and find out he has changed some tables. I confront him, and he replies "but isn't the system object-oriented?". Sigh. When we put lots of data into the database, the system starts working very slowly. He gets angry again. So I look carefully and find out that he didn't create any indexes. In fact, he didn't know what they were. And I was the one who couldn't touch the database, because I might break something! Sigh.
