I while back I posted about being threatened by my nephew and me moving out for my protection. I moved back in after installing a key lock to my door. Anyway the reason I am posting today is because my nephew has taken up a notch. He has become very judgmental about everyone and if you tell him to do something or if he was wrong about something he tells you that you are wrong. Last night he spent HOURS arguing with my parents and insulting them because he felt he knew better than them. He was grounded for a week and my parents had to go run an errand so they roped me into babysitting him and his brother. A friend came over and even though I told him that he had been grounded he sneered at me and left anyway. I am on the phone with my parents now deciding what needs to be done. If it were up to me I would embarrass the hell out of him in front of his friends but my parents think that is to much.
