I was in high school, in band class. Someone came into the band room to tell us they heard on the radio that a plane crashed into the WTC (I went to a liberal high school, if it was your break period, you could hang out in the halls). Everyone was shocked. Then, about 30 seconds later, they come back in and say that it was actually 2 planes. Honestly, we all thought it was a joke they were playing on the radio, since we weren't thinking terrorist attack by that point. We thought it was an accident, and then thought how could 2 planes hit the towers? So we were laughing, saying what's next? Godzilla is going to appear?
The next period, rumors were spreading. 4th period, the principal made an announcement that the murmurs we'd been hearing were true, that the WTC had been hit. If you looked out the windows, you could see the black from all the smoke. We saw the dark skies from band class, but it just looked like it got cloudy, you know? They set up a crisis center in our auditorium since a lot of kids had family that worked in the towers, or family who were firefighters. Teachers didn't even bother trying to teach us, they allowed us to use our cell phones to try to get in touch with our family. All throughout the day, they were announcing the names of students to come to the office, and nobody knew why. One of my friends got called out, and she started crying as she was leaving, since her mom works in downtown Manhattan, but it turned out it was her dad picking her up and let her know that her mom was alright.
My sister didn't have any college classes that day, so she picked me up since the trains and buses weren't running. We got home, and there was business cards and money all over the streets from people that worked in the towers. The money laid there until the wind blew it away. The homeless people didn't even pick it up.
My dad got stuck in NJ since all the bridges were closed. He was stranded with a bunch of other people from his office. They were calling around trying to find a hotel room, but they couldn't find any place that had space or were taking reservations. Eventually, one of the office girls called this one place, and they said they had a couple rooms still available, but there were so many people stuck in NJ, they were doing it as first come, first serve. So then she starts telling them there are 6 of them that live in NY but work in NJ and have no place to stay, and they've been helping with the triage in NJ all day, donating as many supplies as they could. They donated a lot of wheelchairs, crutches, gauze, pressure dressings, etc. since they work in medical supplies. So then the guy agreed to hold the rooms for them. The next day, it took my dad about 4 hours to get home over the Verrezano bridge.
Definitely not something I care to think about, or care to remember. That's basically just where I was, I try not to think about too many of the details if I can help it.
