My rules for her had a lot to do with protecting her from herself. She was very “green” behind the ears and was never aware of her surroundings. When it came to driving....well, let's just say that at the time she would get lost trying to get out of a paper-bag. To her street signs were merely suggestions. She was/is very, very book-smart, but at the time had no common sense (read - immature}.
You know her better than anyone and how she was at the time. So, I’m really in position to second-guess it.
Texas is the only state I’ve been in where perfect strangers wave to you as you pass them on rural roads. It’s a friendly state.
