Now wait a minute. I'm confused. Earlier today I read something written by Chelsea in which she stated that when the attack happened, she was "staring senselessly at the television" in a friend's apartment. Which was it? Was she senselessly watching it unfold on TV in a friend's apartment or was she standing nearby, almost killed by fire raining down around her?
Furthermore, I seriously doubt that if she was standing nearby, almost killed by debris, that she would have been thinking about Bush's tax cut at that moment.
I think this part of the story refers to when Chelsea was "expounding" on the evilness of Bush's tax cuts just as people were fleeing Grand Central Station, which was later in the day (if you believe Chelsea's Amazing Journey, she went from Union Square to the towers, then walked the opposite way to Grand Central Station.) Because people yelled supposedly yelled "fire" while fleeing Grand Central, she was convinced that fire was going to rain down upon her.
Of course, this story she tells completely ignores her mother's lie that she was jogging by the towers, and went for a cup of coffee (or maybe it was drinking coffee while jogging -- they've told so many stories it's hard to keep track!)
