On the other hand, being in jail (with or without lesbian accompaniment) might get her away from a marriage that she didn't really want, and entered into only because she was under social pressure to set a "good example" by getting married and having kids.
That's purely conjecture on my part, and I'm not going to claim that it's anything else. But it has crossed my mind more than once since she got married and had a kid.
And I do know from direct personal experience that if you've been in the habit of partying and drinking heavily, and you get married largely out of a sense of responsibility, then no matter how committed you are to the marriage, it may be a lot easier to deal with it in the short run by continuing to drink heavily, even if you know it's a bad idea and you've said that you'll stop.
If that or something like it is the case, I do have a lot of sympathy for her - although I agree with pretty much everybody that it isn't a good way to handle anything, it's no excuse for drinking and driving (let alone a DUI with injuries + hit-and-run), and she absolutely needs to get off the stuff and get her life on some kind of non-self-destructive track.
