When I interviewed for my current job, my boss saw on my resumé that I'm also self-employed, and she asked about it. I told her that, while I'm not doing window restoration anymore, I'm continuing as a merchant at medieval reenactment events. She thought that was terribly interesting and asked what kind of things I sell.
I've always had slightly odd hobbies and interests, and I spent several years as a tour guide at an historic house museum, so I'm no stranger to explaining things to audiences that might not initially get it, but when the audience is someone who's just asking out of mild curiosity and to be polite, I sometimes wish I had an easier way of responding.
I'll be a little farther north in Vermont this weekend, selling my medieval wares at an event I've never done before. In previous years I've done an event in New York State this weekend, but that state's tax department is an inept, mercenary creature, and after they sent me a bill for an absurd amount that they pulled out of the air with no basis in reality, I refuse to do business there.
And anyway, the event I'm doing instead is much closer to home and has an equestrian focus, so the drive will be easier and there will be horses to admire. I can live with that.
