Sethji’s Promise

Sethji was very sick. He told his doctor, “My sickness is causing me not only physical suffering but also mental confusion. I speak things I don’t mean and mean things I don’t say.”
“Don’t worry. I’ll try my best to cure you,” assured the doctor.
“Will you? Thanks a lot! I’ll donate one lakh rupees to your hospital,” Sethji replied, feeling grateful.
A long time passed after Sethji was cured. One day, the doctor met him and said, “I wanted to remind you that you had promised a donation of one lakh rupees to my hospital when you were sick.”
“Had I? That is the thing! I was so sick that I said things I did not mean and did not say what I meant!” Sethji exclaimed, realizing the absurdity of the situation.
