When I was 10，once my parents were away on business，but I had to stay at home alone for a day.I got up early in the morning，thinking about different activity I could do.The first idea was that I could play computer games all through the day without blamed by my mother.Minutes later，I said to me，“Why don't I do something meaningful ? ” So I planned to cook the meal for my parents.I tried to recall how my mother usually did in the kitchen and arrange everything on my own.With a whole day's effort，I finally made it.I felt it very happy when I saw my parents eating the meal cheerful.They couldn't help say that their son had grown up.
