1. The doctor lived in a room that was full of rats. He could listen the rats all day. There was a regular inflow and outflow of rats to and from the beam. He listens the sound three times and the sound stopped suddenly as rats saw a snake.
2. The doctor took two important and earth- shaking decisions for himself while he looked at himself in the mirror. Primarily, he decided to shave daily and grow a thin moustache. Secondly, he decided to keep an very attractive smile on his face.
3. (i) When the doctor first smiles, he has an blown- up opinions about himself, admiring his looks and profession.
(ii) In the second, the doctor smiles by thinking about his foolishness and helplessness. His thoughts change after he confront with the snake. He accepted his stupidity and moved on from being a proud doctor.
