My first wife had 3 kids, 2 boys and a girl, all were in their teens when I met her, the oldest was borderline emotionally challenged, but still fully functional. he went to live with his father after we had been together for less than 2 years, the second one was somewhat difficult, got involved with an 18 year old girl when he was 15, stopped going to school, except for the occasional day, stole food from our house to feed his "girlfriend", took basically whatever he wanted, whenever he wanted. His mother did little to nothing to correct him, he was her favorite, until one day when she finally had enough and sent him to live with his father as well. The daughter was just 13 when we got together, and was probably the most devious. She seemed on the surface to be very innocent and charming, but at one point she accused us of physically abusing her in the hope that, like her friend, she could get welfare and live on her own, at 15!
The oldest had no clue how to drive, I tried teaching him several times, but he just couldn't get it, literally drove directly into a power pole one day in our alley. That was the last time I took him out driving, his father paid thousands for him to take lessons.
The favorite child had always wanted his mother's 75 Dart, and she was willing to oblige, so I went through the whole car to ensure it was safe and reliable for him, he was a quick learner behind the wheel, but in less than 3 weeks, the Dart was wrapped around a power pole late one night, only a few blocks from our house. I declined to file an insurance claim, and hauled the wreck home, parking it in the front yard for all the world to see what he had done to it. Then I made him help me strip the salvageable parts off it, and drag it to the scrapyard. Not long after that he had gotten his brother's permission to use his car, and totaled it as well. After that he was on his own to buy another car, which he did, and wrecked in short order.
The daughter went through several cars as well, I split with their mother in 2005 and haven't heard from any of them since.
My second wife has 1 son, he was 19 when we met, wrecked his share of cars, and nearly 2 of my trucks, is now 38, and the last few times his mother has spoken to him, he has wished her dead. ignorant bastard.
Apologies for the long winded rant, and kinda getting off track.
