They exercise by playing golf and they go out for meals and to the theater. Sometimes they take me out, too. We have a good time. They also go on great holidays. Last year, they went to China and walked along the Great Wall!Sometimes, my grandparents like to criticize me. They think that children today have an easy life. Life was very different when they were young and there are many things about my life that they do not understand. They tell me, over and over, how they had to start work at 16. They know that I will go on to university and won't be getting a job until I am 22! They also think that I have too many possessions, such as mobile phones, computers and PSPs. When they were young, they did not have anything like that. What they do not realize is that they cannot compare children at present time.
