Millie, 15, writes from Washington DC about her thoughts on the 11 September attacks.
I'm at school at the Mersersburg academy - it's one hour 30 minutes from Washington DC and about three hours from Pittsburgh.
I come from Leytonsville in Maryland just outside DC.
I discovered what had happened from teachers who called a school meeting. I have two uncles who work one block away from the Pentagon. It took about four hours for me to find out they were OK.
I'm very confused and angry but I think Bush should wait and make sure he knows who is behind the attacks before the US takes action.
Quite a few of my friends come from Boston and were really worried they might have relatives on the flight. Luckily everyone seems to be OK.
My school has a TV room - it's on all day and students keep on popping in to check on developments.
I can't believe that someone could do this to the US and kill so many people.
I've visited the Pentagon and the twin towers and am shocked that such a landmark could be hit like that.
