Once when l tried to fry some bread 🍞 for my self my sister offered to help me But l refused her offer as l wanted to do it all by myself. She got annoyed and left the kitchen. l put some oil in the frying pan 〽️ and heated it. Just then l released that l wouldn't be able to fry the bread and called my sister for help. But she refused to come. After calling her repeatedly she came to the kitchen . But by then the oil had got heated and had caught fire . We didn't know how to put it out so both of us stood and watched it helplessly . My mother came running and asked me to cover the pan so that the fire would not get oxygen and would get extinguished. That day l learnt that without the presence of oxygen there can't be a fire🔥.
