text: Also, If a student is already participating in activities he or she may not be able to attend these school activities that the principal is enforcing. When my principal started the rule, I had soccer practice everyday right after school. When he announced that everybody has to participate in a activity after school, I didn't know what to do. I talked to my mom and she said that she won't allow me to stay after school to do something my principal wants me to do. She'd rather pay for something I liked doing and that was soccer.
