I was living in California. My ex woke me and my step son up, saying a plane flew into the WTC. As we were watching that at 6:30 am, we saw the 2nd plane hit.
My ex and I were working for ourselves at the time, (landscaping), so we went to work. One of the clients we saw on Sept 11th was a couple from Danville. When we saw them, they were both white as a ghost, and the wife was nearly in tears. When we asked what was wrong, they told us that they were in NYC visiting their son in college, and they were deciding to take the red eye back to San Francisco, or take the first flight out the next morning. The wife wanted to be home to oversee the lawn install on their backyard renovation, so they decided on the red eye. The first flight out the next morning would have been Flight 93.
My ex was upset that Starbucks was closed on the 11th. She was in denial about the whole thing until the following Monday when the A's played the Yankees in NY. She couldn't stop crying the whole game.
