I usually draw in silence, but listen to music or public radio when I'm painting, after all the important decisions have been made.

Odd things happen in New York, which is why it's such a great source of stories.

But mostly I think two people do share a moment, and we all know that feeling, and it can put a spring in your step for the rest of the day.

I toyed with making portraits based on people's discarded shopping lists found on the street, or old diaries bought on eBay, or other forms of borrowed stories. When I stumbled across the Missed Connections listings, I knew immediately I'd found it.

Someone wrote to me asking me to illustrate a missed connection that "hasn't happened yet." This guy has seen the same girl waiting at a bus stop on his morning commute for weeks, and has been trying to find a way to approach her. He thought it would be fun to put up a Missed Connections poster [of my painting] on the corner where she waits and see what happens. It is kind of an intriguing idea but there's something a bit too manipulative about it for my liking. It's a fine line between being creative and stalking!

Many messages are just thanking a stranger for a kindness...I love those ones, because I imagine everyone else reading them feels encouraged by such examples of humanity and generosity and tenderness. And if they encourage us to reach out to strangers more often, that's a good thing.

There are also dozens and dozens of success stories; many couples have emailed me with their original posts. I love reading these stories, but confess I am not as interested in drawing them as the unfinished, elusive ones.
