A few weeks ago, in a cavernous convention centre, 2,507 people from 121 different countries took the oath to become US citizens.
Hundreds more sat at the back, family and friends, beaming and buzzing with anticipation, ready to celebrate their loved one's landmark moment.
It was an extremely moving day – and the end, for many, of a long and fraught journey.
It was also very inspiring – and I know because I was one of the 2,507.
Every one of us in that crowd had our own story about how we had come to be sitting there, with a little hand-out Stars and Stripes flag, as newly-minted citizens.
At its heart though, the ceremony was a powerful demonstration of what America is: a melting pot of diversity where tens of millions embrace and accept each other irrespective of origin, race or religion.
In a week when division and violence again dominates America's news agenda, the beauty of that ideal is worth clinging on to.
