although I don't wake always at 5:45 these days... some days yes, other days who knows?
I got a call from my daughter, "Are you watching the news?". Turning it on, like Mama, I saw the smoke from one tower... and was watching when the second tower was hit.
I was pretty convinced it was a terrorist attack as soon as I turned on the TV... and to this day I find it odd that the announcers were extremely cautious in speculating, and this even after the second tower was hit. I think, perhaps, no one wanted to believe what was obviously true.
