I was a junior. I went to a boarding school and one of those weird memories that sticks with you is that I was unsure whether or not to go to my classes. No cell phones and pretty primitive email system, so it just wasn't clear. I went to one at like 9:30 (central time) and nobody was there, so that was when I realized "oh this is one of those nothing-is-normal-now things".

I was a senior. I grew up on the west coast, never been to New York, but my English teacher was from New York. She knew she'd lost friends that day, but not which ones. She held it together, but it really added a personal connection to what would have just been a horrifically impactful event on TV.
