I think I just leveled up.
Longing for a change of scenery, I took my laptop to my favorite local coffee shop this afternoon so I could write and enjoy a steamed coffee-like beverage. (Since I'm still trying the 'no caffeine most days' thing, I went with a cinnamon-chocolate steamer, which was excellent.)
A man came in and started chatting to the people at the table beside him. I kept working and occasionally looked up. Then they left, and he started chatting with me. He asked if I like my Mac, so I talked about how much I like it, and about how much I like Scrivener, because I'm a writer.
Which led to him telling me about how he tried writing a novel once, and he couldn't finish it, and then he said, "I thought I'd just tell a writer my idea."
A complete stranger told me their idea for a novel with the implication I should write about it. That's never happened before. I kind of hope it never happens again...
Though I did meet and exchange cards with another local writer, who's working on a memoir, after she overheard us, so it wasn't a total wash. And I did get some editing done.
