As Whanganui resident and New York ex-pat Kathy Cunningham says in our story marking the 20th anniversary of the September 11 terror attacks: "I will never, ever, in a million years forget that moment."
None of us will.
The footage of planes flying into those buildings.
The President having the news whispered in his ear in a classroom not dissimilar to the one I spent that day in.
The sheer amount of rubble that rained down on one of the most recognisable cities in the world.
They were images of chaos, absolute destruction, death and terror.
We spent the day at school watching the coverage on TV and each day, for weeks after, I cut out every newspaper article about the attacks and pasted them in a scrapbook (I suppose it's no surprise I've ended up in this career).
The whole thing was utterly inconceivable but that didn't stop me trying to wrap my head around it.
I don't think I've got there yet.
Twenty years on we can reflect on the lives lost, the political impact and the consequences still being felt.
But that real world stuff is for people who were more immediately impacted and people with more expertise than me.
For most of us in New Zealand who woke up to the news, and went about our day, we will be thinking back to that "where was I?" moment and what it meant for us.
I suppose after September 11, 2001, the world seemed a bit more vulnerable. It takes a bit more to be shocked now.
Most of us will never fully comprehend what happened that day - but we know the world wasn't the same after.
