I was 4 blocks away at 100 William Street. I got in early(8am) because as always I had some homework to finish. I finished the homework and went outside for a cigarette. I came back and people started coming in and saying a plane had hit World Trade Center. At first I thought it was a joke, then I thought it could be a pilot error. People started crowding around the TV. I called my dad because my mom was coming back from Russia that day and he was supposed to pick her up. Still not realizing completely what had happened I told my dad to rush to the airport because there could be some extra traffic as a plane had hit World Trade Center and I did not want my mom to be stranded. My dad didnt believe me but then he turned on the TV and saw for himself. At around 9:30 the buildings started collapsing and the debris was hitting our windows. The reaction was to look outside at what was happening. A manager said to get away from the windows(good call because the debris could have penetrated the windows). A decision was made to evacuate the floor. So we got up and started making our way outside. We came outside and it was strange, there was debris floating in the air, it looked like snow except you knew that it wasnt. We started making our way towards the Brooklyn Bridge(I lived in Staten Island, so it was a logical thing to do). One of the lunch places we would normally visit was handing out water to passersby, I took a few, just in case. As we walked up to Brooklyn Bridge we saw people running back. Deciding it was better to walk elsewhere we went to the Manhattan Bridge instead. People were tired because at that point it was a few hours of walking. While we were on the bridge, the group I was with, decided to rest there, I said that we should keep walking, at least until we crossed the bridge. I was not sure but I did not want to stay on that bridge longer than was needed. We got to someone's apartment in Brooklyn, close to the bridge and called a car service to go to Staten Island. The driver would only take us as far as the Verazzano because he was not sure if he would be able to come back to Brooklyn. I was with several people going to Staten Island and I called my best-friend(I could not get a hold of my dad due to phone problems), his mother picked-up and cordially invited me over. I made sure the people got on the Staten Island buses and from there took a bus to my friend's house. The driver did not even charge anyone a fare. I bought a six-pack on my way over, came inside, drank 2 bottles and fell asleep. The next day my dad picked me up and said that my mom was in Canada, she would be there for a week. I was home for about 1 week and then went back to work.
