When my mother played the footage for her, she fell completely silent. She couldn’t argue anymore.
My mother firmly warned her: "From now on, stop making baseless accusations. This kind of behavior will only make people resent you. I’ll let it go this time, but if you ever falsely blame me again, I won’t stay quiet."
Embarrassed, my sister-in-law made an excuse to take her daughter to her parents’ house. Just now, she texted me, asking me to request permission from my parents for her to stay the night there.
When my brother found out what happened, he was completely fed up. My mother suggested that he and his wife move out—rent a place if necessary—so she wouldn’t have to deal with the stress anymore.
