So, my mother-in-law came to stay with us for a few weeks till her home is renovated for Christmas. The problem is, she has been randomly walking in on me while I'm in the bathroom. Thankfully, not once has she seen me naked because I started picking up on her behavior after the second time in a week. She barges in, then turns and says, oh, sorry, then closed the door. I tried talking to my husband about it, but he kept ignoring me, then flat out said, so what if she accidentally seen you naked? She's family. He seriously said that. We have a lock, and I could have used it, but I have past trauma from the idea of locking and being locked in a room after my brother locked me in the bathroom when I was 5. So, I came up with this idea. I go inside the bathroom, pretending to use it, and wait for her to come. When she accidentally barges in, she sees me in a weird and awkward position. For example, doing a ballet stand, standing on the toilet, or standing facing the walls with my hands up. I could see how awkward and weird this would be for her because she's standing there for a few seconds trying to figure out what I was doing. It was hilarious at first seeing her initial confusion, but she told my husband about it, claiming she's caught me practicing rituals in the bathroom. I clear things up and reveal the reason why. My husband was livid. He called me childish and said I made his mom feel terrified and weirded out by my behavior. He said I should have acted maturely and locked the damn door instead of playing mind games.
