Corrected essay:
Everyone has an experience of staying at home alone when his or her parents go out.
I once stayed at home by myself. But I didn't want to be alone at home. Because I depended too much on my parents and couldn't be away from them. But one day, my parents had something important, so they had to leave me alone at home. I wanted to go to school but had to stay at home alone. On that day, as soon as I came back home from school, I happily threw my schoolbag on the sofa and ate lots of snacks. Then I enjoyed an exciting film on TV. Next, I played games on my mobile phone. After a while, I was so hungry that I wanted to eat something. I was about to cook dinner but I found I could only do some simple cooking. So I made some simple dishes. But the dishes were not delicious. I started to feel lonely. I wanted Mum and Dad to come home soon. Because I couldn't take care of myself well.
I think being home alone is not always perfect, but we shouldn't depend too much on our parents. We should learn to look after ourselves.
