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.

But yeah, that's just life I guess.
