You guys probably have seen this blog before, Missed Connections, by Sophie Blackall, but I recently just stumbled upon it & adore the concept. Sophie illustrates beautiful, sweet, & funny... missed connections. Hundreds of people write in & attempt to reconnect with people that they wished they had reached out to... on a train, in passing, from a quick glance.
It reminds me of "Serendipity" lived out in everyday life. Love it.
