...Eh, I thought the title was funny. I recently finished scene #13 in my wip. Obviously, because it was scene 13, things weren't going to go as planned. (If you aren't scared to death of the number 13, then... Well. I pity you. But back to our story.) I wound up deleting the last 1600 words of the scene and writing them over from scratch. Thing is, all the information in the original version is important, probably bound to be canon, and it was nice to know it. Normally, this would mean I'd need to keep a copy of the original scene around someplace in a scraps file, or at the bottom of the document, or... Wherever. This novel, however, is stored in a version control system called git, so I've already got a copy of the original scene as it was when it was committed, and I'm free to delete the thing and start over any time or any way I like. Quite pleased with that!
