While hunting for our Paris apartment last June, a redbeard was spotted. Not on a Frenchman, but what was very obviously, a tourist. He was staring at the Palais de Justice with a gaping maw (or perhaps just yawning), when I found him. I probably should've approached, it's very possible he spoke English, but I think I was in a hurry, off to the next apartment viewing. And the tourists here take pictures of absolutely everything, often with a selfie stick, so I have no shame in taking pictures of them.
I was with my father-in-law at this particular moment, so I had to explain why I was photographing random tourists. Some people find it very odd that I collect photos of redbearded men, but I believe it's good to have a collection of something. It keeps you curious and seeking new experiences. I collect redbeards, and also crushed pennies.
