My opinion is sure to be unpopular with many.
My office building was across the street from the WTC and badly damaged. It goes without saying that I knew a couple of people who died that day and many more who had harrowing stories and losses of their own (I was scared but never in actual harms way). It was eight months before we could return and I had to look out over the terrible remnants of the site and the new construction for years afterward.
There will be respectful and appropriate ceremonies on Monday in many places in the area and those among us who want to participate, can. I will. But for me, 22 years later, I don’t want to be reminded of that awful day every time I turn my head from now through Monday.
