What would you do if you were in their shoes?

There are many codes on students' behaviors or appearances in schools. In my school, many teachers have some conflicts with his or her students because some of the students do not want to get their hair cut as the codes say. If you were in their shoes, what would you do?

What can I do?

My son asked me to buy him a 'Sudden Attack Computer Game' CD. He said that most of his classmates play the game and he has to participate in the game to make friends with them. I understand what my son says. But I think that the game is too cruel for the elementary school students to play. What can I do?
