That day started rough. My son was 8 months old, and never slept more than 3 hours at a stretch. That night and early morning had been particularly bad, and my wife was at her wits end. She left me alone with the kids at 4 am and went to out to the beach to walk and nap and try to collect herself. The kid went to sleep for me, and was still asleep when she got home just in time for me to head to work. I was scheduled to give a tour to major donors at the historic site I was curator of at 9:00. As we left to begin, one of my staff members said "there is a report the WTC got hit by a plane". We went on the tour and peoples cell phones started blowing up about 5 minutes later. We decided to cancel the tour and headed back to our offices. As I walked in my agency head yells at us "WE ARE UNDER ATTACK THEY HIT BOTH WTC TOWERS!! and he sent everyone home. We went to the closest staff members house about a mile from work and got in front of a TV just as reports of the Pentagon getting hit came in. Watching both towers fall on TV is still one of the most surreal things ever.
