One morning that I was in primary school, I tried cooking for first time. As my parents weren’t in, I have to cook something to eat. I took an egg from the refrigerator, putting some oil in the pan and cracked an egg into it. After a few second, I tried to turn the egg over in case it would get burnt. Unexpectedly, it caught fire. Not known what to do, I screamed but rushed out of the kitchen. After a while, I realized I should put out the fire, so I returned back, only to find something but a black burnt egg. I’ve learned that I can’t be too carefully while cooking.
