He is 12. His brother is 9. His brother is always calling him names and annoying him. So now 12 year old is always saying "im gonna kill you". Now I know this is normal behavior cause he is mad. Today I found a note in 12 year old's room that said" I killed my brother. Are you proud?"
This does not sound like normal behavior to me to write something like that. I am scared now. What do you think? This happen to anyone else? Should I be concerned? Take him to a therapist?
