If she's rude to you, give her one word answers like "Uh huh." and walk off. Pull a prank where you don't get caught. Be exceptionally nice to her and keep smiling like you're happy af; or ask her a billion questions and talk her ear off. Just make sure they're appropriate to work, or if they don't have to be about work. Just gab about a "fake boyfriend" or a tv series or politics that are appearing and don't shut up like an annoying valley-girl kardashian. You could also completely ignore her as much as possible and go out of your way to not have to be near her except for work stuff. Hope that gives you some ideas.
