Photographed in Prague, Czech Republic December 20, 2010 A decade ago, just weeks after I turned 20, I traveled to Prague to study for a semester. I returned to the city for the first time last week to celebrate my 30th birthday. On my trip, I had a happy realization that I both started and ended my twenties in the same city. And it is comforting to know that, despite many of the glaring changes, the city underneath is the same now as it was then. I suppose if it has been able to withstand centuries of change, ten years is nothing.
