September 4, 2017. About Me. I made a mistake. My appointment at NYU School of Dentistry is not September 8th, the day the movie 9/11 opens in movie theaters. My dental appointment is tomorrow. I would have missed my dental appointment had Brandon Ash not telephoned me earlier tonight and asked if I could come in later tomorrow rather than at 10:30am as scheduled. Why did I think my appointment was on September 8th? How could I forget that my appointment is for the day after Labor Day? Why did I not realize, when the appointment was made for me, that my dental appointment was scheduled for the day after Labor Day? How could I make a mistake and forget to pay my new monthly rent, $731.37, Oklahoma City zip code? How many other mistakes have I made?
