My mother-in-law lives in the new house. I don't feel well. Is it petty?

Haha, to be honest, maybe a little narrow-minded. I bought a house last year and decorated it for several months. No one had lived there at that time, including the bathroom. That day, a master went in to go to the toilet with an anti-theft net, and I didn't clean it. I was very upset when I saw it. The house I bought was just renovated and I haven't experienced it yet, so I found an outsider to open it first, and the bathroom stinks, but I don't want to. Just like you, you can find a way to move there yourself as soon as possible. It must be uncomfortable for others to experience the house you worked so hard for. Not too narrow-minded, but your mother-in-law is too unreasonable. Ha ha laugh
