I taught high school students

It was an accident, I became a teacher. When I was passing by government school, i saw a strike by 10th class students. They were demanding mathematics teacher. There was no person available to teach them that subject. I thought, “let me try a little”. The  next day I went to the school and started taking classes. “Something is better than nothing”  was the policy. The headmaster allowed me to conduct the classes. Slowly i picked up in the teaching process and i used to take classes regularly to 8th, 9th and 10 classes,  as per school time table. This practice went on for almost two years. I was not a professional teacher. I was never trained to teach. Yet, my enthusiasm worked and made me a teacher.
Students started to visit my residence, to learn basic skills in mathematics. People started to address me as teacher. One fine day, regular mathematics teacher was posted and I was relieved. But a science teacher was pregnant and went on maternity leave for six months. I started teaching science as Science was my hobby. It helped 10th class students to clear their SSLC result. I was not asked to work as a teacher, but I did all this as a voluntary service without taking or demanding any salary or honorarium. I used to live in my sister's home and would get my food needs their.
While teaching I was also learning. It benefited me too. When science teacher returned  after her leave, we both used to discuss on mutually interested subjects, like biochemistry. Thus almost four years I was at that kind of work. Thus i too became a teacher. Sometimes I used to take classes on English grammar. English teacher encouraged me to carry on the practice. She appreciated my effort in teaching English grammar. My retired life was well utilized to serve the needy in rural environment. One fine day headmaster called me to his chamber and asked me to discontinue my teaching activity. I obeyed his instruction and stopped attending school on a regular basis.
Science teacher was reading for her PhD and she was in need of my experience on science, especially electronics and applied science like communication and all. We used to sit together and read and discuss the related topics. She was very much pleased when she cleared her theory portion of her PhD course.
