I wear a hat to bed in the winter, and use a sleeping bag as a comforter. This lets me turn the heat down at night, thus saving money for more entertaining things than heat. My favorite hat for these purposes is a thoroughly goofy thing I would never, ever, ever wear out in public: it's blue and white with a pseudo Nordic sweater print, a big pom-pom, ear flaps, and (at the ends of the ear flaps) two long blue and white yarn braids, like ragdoll hair. It's wild, but it's warm
So...Saturday morning, I get up relatively early, and--still wearing my goofy hat and my long johns--become engrossed in messing around on the mandolin. I found a really neat Russian klezmer-ish sort of tune and was all but dancing around the living room with the mandolin going to *town* on that tune (not your typical fare, but ooh, it's fun stuff!). And then there was a knock at the door.
My landlady wanted to let me know someone would be by soon to work on a minor plumbing issue. She was nice enough not to comment on either my attire or my odd choice of noise-making.
I have no idea what she must think of me now.
