My son shared with me today that a few boys in his class keep raising their middle finger at the teacher when he is not looking. How do I deal with this? Should I inform the teacher, or simply just educate my child on what is right and wrong- but this makes me feel like I am doing wrong by not alerting the other kids' parents on their behaviour. On the other hand, if I inform them about this incident, my son may not trust me again. Help!
