Learned a song in open D and my fingers are confused

Spent yesterday afternoon re-tuning to open D to get that drone-y, molasses feel on a Tom Waits tune. My fingers keep reaching for shapes that don't exist anymore, and honestly it's the best kind of lost I've felt in weeks. Played it on the corner this morning and a guy in a delivery van rolled down his window just to listen, didn't even buy anything. That's the whole win.
