I was in 7th grade english... another teacher came to talk to our teacher... she got really quiet and eventually went to the back of the classroom and turned the tv on. I remember seeing the smoking building... and not really thinking much about it at the time. (I mean, no one was saying anything to us and the tv was on the other end of the room) We just sat there until the bell rang. My next class was math, and our teacher there was also staring directly at the tv.
Around that point, (I'm guessing) the second plane hit the other tower, because mrs benson got up and turned the tv off very quickly and over the intercom came the announcement that school was letting out early and for everyone to report to the lunchroom to wait on the buses.
The lunch ladies passed out what little bit of muffins and cookies and whatever they had before we went home, I guess they had to feed us something... none of the teachers said anything... although some were crying... no student seemed to know what had happened, all the kids were just celebrating getting out early.
