公公替大姑姐一家訂下我家客房，我沒反駁，臨出發前把行李箱推到老公面前：這次你們自己招待

My husband's older sister and her family said they were coming to escape the summer heat, and my father-in-law, without even asking, arranged rooms in our house for them. My husband just told me, "We're all family, just bear with it," as if cooking, cleaning, hosting, and serving the whole family was my responsibility. I didn't confront them on the spot, nor did I argue about who was right or wrong. Until the day before they arrived, I pushed my suitcase in front of my husband and calmly told him: "You'll have to take care of them yourselves this time." They assumed I couldn't leave this family, and that I would always clean up everyone's messes. But true boundaries aren't established through arguments; they begin the moment I turn away.
