A: It must be strange right now in NYC.

L: What's strange is I almost forgot until just now. It's strange how something that huge happens and then when so much time has passed since the event, you begin to forget it and see it and feel it in a different way. Kind of like breakups, or traumatic life experiences.

A: I mean there were just so many momentous events in history, people cannot remember all of them. I remember that on the centenary of the outbreak of WW1 (which was by far the most important event for Europeans in the 20th century, or ever) barely anybody noticed it. But yeah, that's just life I guess.
