The north tower has collapsed.

I go back to my desk, as there's nothing new to be gained from CNN.

Our call volume has gone to nearly zero as the northeast telephone system is swamped. An outgoing call can take five to ten minutes just to get a dial tone.

A coworker and I go to Applebee's for lunch. It's nearly empty and CNN is on every TV. At some point they turn off the audio and turn on their music. I ask them to turn the TV audio back on and they agree.

I spend much of the rest of the day talking to clients with little sense of geography; they ask if I can see the towers from my office, if anyone I know is/was there, etc.
