I was sitting on the toilet doing number 2 when I heard that a plane crashed on a tower of the World Trade Center. I cut it short, ran in the kitchen to watch what happened on the small TV on top of the fridge. After a while I decided to finish my business so I briefly looked at the TV when I saw a second plane hit the other tower. I spent the entire day watching the coverage in the living room. I wasn't working on that day so it was a very long and sad day for me.
Sorry for the details but that's the way it happened for me on that horrible day.
I can't even remember what I was doing on 9/11. Besides I don't live in the US so it didn't really affect me in anyway. I was probably in school at that time.
