A boy ducked below a prop wagon on the streets of Mountain View, looking to investigate its less-than-authentic wooden spoke wheels. The sign read "Calendars" and the front of the cart had editions featuring cats, elephants, americana, and photos from places most people will never get to visit.

"David, come out of there." called the dad. The boy smiled an adventurous grin as he took his time. I smiled at their antics, and kept walking.

Ten minutes later, I round a corner and see the duo at it again. This time, David's picked a string of lights in a shop window as his muse. His father seems more accepting of this selection than David's last.

I point to the camera, and whisper to the father for permission to take a photo. He nods.

And that, is how I met David.
