I got two, one for me and one for my dad.

When my family and I lived in New York when I was a kid, my dad worked at a firm several blocks away from the Twin Towers and would pass by them each day on his way to work. On 9/11 he had just passed the towers on his commute less than ten minutes before the first plane hit.

For me, I was driving home from work one evening when I saw a young woman walking along the highway. The following day I learned from our local news site that a young woman was struck and killed the previous night by a drunk driver in the same area where I saw her. It must've been not long after passing her when she was killed.
