My weirdest memory from that day, is walking downtown towards the burning towers.
There was this huge plume of smoke in the air, and the streets felt really eerie with no cars on them. There were a fair number of people out and all walking south, but NY was really quite with no traffic.
We were walking down the middle of the road.
Then, sitting on a wall or something, I forget, was a guy who wasn't looking at the towers. He was facing the people, and saw me and my friend.
"Hey, pretty ladies!" he said. Standard low level street harassment on a normal day - BUT DID HE NOT CARE ABOUT THE CARNAGE BEHIND HIM?!!!
Seriously, WFT? That truly boggled my mind. No one knew what was going on, it could have been WW3. But this guy was like - another day, another pretty lady.
