The mental hospital,was a new psychological doctor.
Doctors found a patient,every day hold an umbrella in the corner of the room,crouching,neither ate nor drank.
The doctor cured the patient to think,to understand the inner world of the patient,and patient.
Hence,the doctor wanted a way.
The next day,the doctor also hold an umbrella,sitting on a patient's side.
Patient watched him,don't talk.
One day,two days.
Doctors are quietly sitting on patient,full of umbrella,not to talk.
On the third day,patient finally turned oddly ask him:you are a mushroom?
