Pain

Prior to Board examination I got 18 days for study leave. During this time my sister's annual examination was going on. My father told to teach her one day before math exam. So I started my classes at morning 9 am.

At the beginning she grasped the lecture at a very fast pace slowly, slowly it slackened. When she didn't understand I tried to explain the concept in a very simplified manner. At last I finished my lecture at 8:30pm.

After that I was extremely tired. I was having some problem with my throat.The next day I was having high fever. Doctor told it is due to over-strain. Then I realised pains and difficulties faced by our teachers.
