Is a posting on some website chatroom confirmation of anything? And I've seen more than one interview of friends of Natalee saying she told them she would be hanging out with Joran. Her friends even say she was drunk. I wouldn't take anything on a website, or for that matter anything her friends say (they all have a different story)without a grain of salt.
The Alabama classmates of Natalee are very poor witnesses because they all admit to drinking that night, and some admit to being intoxicated.
Teenagers drinking "resposibly"? Hardly ever happens. Especially in an environment where they are far away from parental supervision.
Well, it would be helpful to at least see that it was the friend saying it wouldn't it? Anybody can pretend to be anybody in a chatroom. People claim to be friends and relatives of principals in cases all the time on here.
Go catch up. Read through the threads.
