I've had my 16 year old Granddaughter off and on since she was 3 months. I'm her Mom since both her mother (drug addicted) and step mother (bi-polar problems) have not been. Her Dad, my son, is dealing with single parenting my 14 year old, bi-polar, grandson and it's taking all his patience and time. So Rae s with me we get along well,. She's a blessing. 
 
Within the last month we took on Dan's 15 year old grandson. The boy's mother "slipped out of town" here last year to get away from debts and a bad reputation. She headed to FL to live with her mother. The boy was having problems at home and in school. He was in trouble because of attitude and being disruptive so she sent him back here to us. She didn't tell us that this. We found out after he got here. He hadn't attended school for at least the last 2 months he was in FL and even though I E-mailed her the phone #, address, and name of the Administrators of the school he'd be going to he didn't have the proper legal paperwork he needed to be enrolled in school here when he arrived. So we are working on this. So far he's lost at least 3 months of his Freshman year. And schools here have only 2 months left until school is over for the summer. 
 
He's sullen and angry most of the time. He does whatever he can to upset my granddaughter. Spying on her and her boyfriend, even setting up a hidden vidio camera on them one time. He makes rude comment and is constantly snide and difficult. I know he is homesick but he calls his mom and demands money then hangs up on her. He is distructive if he doesn't get his way. 
 
Dan has Cronic Obstructive Lung Disease and is on Social Security Disability so he's not up to keeping this boy in line. We paid $250 for a airplane ticket for him to come up with his Grandmother when she came to visit her mother. We have almost $1000 invested in getting his custody straightened out so he can go to school. I can see how taxing he is on all of us and I'm ready to chuck it all, pack his bag and put him an a Greyhound headed for Ft Myers.  
 
I raised 2 boys and never had this problem. But then I had a chnce to work with them from "birth" where this one has been spoiled and allowed to pretty much do as he pleased for 15 years. He's a 6'1" 280 lb bundel of aggrivation with size 12 feet.  
 
Has anyone got any ideas?? I'm open to any help.
