My younger sister-in-law lived in my house for thirteen years without paying a cent. She ate my food, used my things, and never even bought a single roll of toilet paper. When she finally got married, I gave her a generous wedding gift of 88,000 yuan, thinking I could finally put those thirteen years behind me. But my brother-in-law's debts, along with two loan guarantees my husband had secretly signed, suddenly became my responsibility overnight. Creditors came pounding on my door, my mother-in-law brought people to inspect my house, and my husband casually suggested using the house to pay off part of the debt. So I dug up every account from the past thirteen years and made them all settle it, one item at a time.
