Is OTHER wrong in the post ? POST : My mother-in-law moved in with us about three months ago. It's been ok. She and I are clashing personalities and cultures, and it's come up more often now that we share a similar space. She is a traditional Hispanic woman with a strong sense of decorum and family hierarchy. I am white, liberal in all ways, and agnostic about most traditions, including and especially the need to obey elders.

Before, out of consideration to my wife and out of a belief in the my "my house, my rules adage," I used to watch what I said around her very carefully because we only visited with her about once a month. But when my spouse asked if she could live with us, I said I was okay with it as long as I no longer had to walk on eggshells around her. My spouse agreed and told their mother that she needs to respect that we do and say things differently in our home than she may like. I don't know how her mother responded to that but it never came up again.

Last week, my 10-year-old and I were chatting while having breakfast while she was in the kitchen. We were goofing around and making bodily function sounds to each other. We are very mature, I know. But when I said, "I fart in your general direction!" and made a loud raspberry sound at her (she was giggling like crazy), my mother-in-law slammed down her coffee mug and said, in Spanish, "Don't you dare teach my granddaughter to be so disrespectful. I will not allow this kind of vulgarity in my home any longer." And I said, in English (I can understand Spanish but can't speak it well), "This is my home. You don't get a say in how I interact with my kids, or how any of us speak or act." She stormed away and now isn't speaking to me.

My spouse says ITA because I embarrassed her in front of our daughter and because I expected her to accept too much, too quickly. They also say that I am being a little culturally insensitive and that I need to respect that abuela will be deeply offended by how I spoke to her, so I need to apologize. But I think it was important for her to see that I will stand up for our interactions/myself and also to stick to what we originally agreed on--that I won't be policed in my own home.
