I was in grade 11 (or was it 12?) fine arts class. The moment it happened I was smoking right before class. I came in and people asked if I'd heard, and I didn't know what they were talking about... we watched it on the news and my teacher was so paranoid, even though we were in a different country.
I didn't believe it at first... I remember it was surreal watching it unfold. The footage of the people jumping out was just terrifying, all I could think of was what they were thinking/feeling right there. Surreal is probably the only word to describe that day.
