I was in my Precalculus class in high school (I was a junior). I had finished my work in that class and was grading some papers for the teacher (I doubled as his assistant for the class, since I had the best grades out of any of his classes), which I tend to zone out during. I looked up and everyone was gone, and it wasn't time for the bell to have rung yet. I checked the class next door, where a few classes were packed in as everyone watched the news.

An hour or so after the second plane hit, my mom picked me and my sisters up from school.
