I am very worried about my 12 year old (soon to be 13). He really does not have sense of right and wrong, anytime he does something bad he either lies or if he does apologise and you later go to discuss the incident with he him he says it wasn't that bad. He is really frustrating and worrying me, particularly in terms of school. One of his teachers commented that he does not take responsibility for his actions.
Any advice would be appreciated.
