TWO MENTAL PATIENTS

Okechuku & Ngozi were patients in a psychiatric hospital. While moving along a swimming pool, Ngozi fell off into the pool.
 Okechuku bravely went after and saved her life. When the director of the hospital learnt of his bravely act, he decided to discharge Okechuku, believing that only someone of normal mentality could carry out such a brave act. So he went to announce the good news to Okechuku. Here is their conversation:
-   Director: Okechuku, I have two news items for one. One is good and the other is bad
-   Okechuku: Yes oga, start with the good one
-   Director: I shall discharge you from here today because of you bravery in saving Ngozi’s life!
-   Okechuku: Hmmm interesting, and the bad news now?
-   Director: Unfortunately, Ngozi whose life you saved killed herself by hanging in her room!
-   Okechuku: No, she did not hang herself; I tied her there so that the water on her could dry off!
