One possible version:

Everyone may have the experience to stay alone while his or her parents are out.

One day last year, both of my parents went out for their business. So I had to live on my own. I went to school and came back home as usual. I cooked dinner for myself, did my homework carefully, and went to bed on time. When my parents came back, they were happy to see I was able to take good care of myself!

I think we shouldn’t depend too much on our parents, but learn to stand on our own feet. Nothing is impossible if we try our best.
