I've got a couple of links to old posts of mine to share with y'all.
The second is my post last year about how I found out about the attacks.
This year I'll share another story I just thought of.
I had a substitute teacher later that school year for World Geography. She'd worked for either one of the big banks or brokerage firms (I forget which) and was supposed to be at the World Trade Center for an early-morning meeting on 9/11, but something kept her from going. I think it was that one of her kids was sick, but I don't recall for sure.
After that, she realized she must have been meant for something more, so she quit that job and was getting into teaching.
