There are a couple of posters on this thread that are discussing the age when one becomes RESPONSIBLE...
I think at different ages, one is responsible for different things, but the very second that a girl/woman becomes pregnant, she becomes responsible for another human being...
IMHO, that responsiblity can be carried out in different ways...for example if a girl gets pregnant and is too young to take care of or even want that child, it is her responsiblity, IMHO, to physically take care of herself long enough to give that child a healthy start, and then place the child in the home of a couple, who can't have their own child...
In this case, sure Natalee had the ultimate responsibility for herself, but I still think that one of those chaperones should have been at that bar, and taken it upon himself/herself to stop her from going in a car with a boy she barely knows!!!!
I agree...the chaperones should have been more responsible. I pray for this girls family...I know they must be in terrible pain!
