Beth now "knows" that's why Natalee got in the car. She thought it was a cab. Amazing how she can get inside the mind of her daughter on the basis of anecdotal evidence.
A few days ago, Jug Twitty, answered that Natalee went to Aruba to 'have a good time'. Evidently hooking up with a tall good looking boy was part of the good time. My guess is that she was flattered by the attention of Juron and alcohol lowered her inhibitions.
