We have a 21 yr old physic's major who in the spring said he was burnt out even though he was 4 classes away from graduation and did not want to return in the fall,and he did not. He is working part time and lives at home with us and his siblings.he pays his own bills(car insurance,cell phone, clothes etc.) and enjoys his younger brothers. He is very smart and was raised to be polite and courteous which he has been. I will say my wife and I have been bugging him to get a gameplan and lately every question as to his future is answered with a shrug of the shoulders.Well the other day he just packed up some clothes and left without telling anyone leaving a note saying he needed to find his place in the world.(He got that from me) He apparently went back up to his school and is renting a room from his grad.student friends. The problem is that he won't talk to us...won't answer our phone calls or texts.He said through a friend that he isn't mad at us or anything but he refuses to communicate with us. He is comming home for the weekend to work his job but told friends he won't stay here...totally out of charactor.We are a hard working Roman Catholic family who is very close and do almost everything together..don' t get it
