The walk was not scenic but it was beautiful. And it was sad. It was through some extremely poor/low-income areas and I lost count of the many mattresses and makeshift sidewalk homes I'd pass on my way each day, the piles of garbage, the struggling mothers all hurrying their kids to school down the block. And the contrast of such surroundings with the people I'd encounter only minutes later sitting in beautiful conference halls, working on their MacBooks, answering emails on their tablets and having conversations on their smartphones was jarring at the very least.
