What would you do to your ex if they were shrunk to one inch tall and trapped in your room?

If my ex were shrunk to one inch tall and trapped in my room, I would first ensure their safety and well-being, as it's important to treat everyone with respect, regardless of past relationships. I might find a safe container to keep them in while figuring out how to return them to their normal size. It would also be an opportunity to communicate and resolve any lingering issues, albeit in a very unconventional situation. Ultimately, my priority would be to address the situation responsibly and compassionately.
