A week ago, my DIL came to me in tears and asked me to watch my 3 y.o. grandson for 5 days because her mom had gotten very ill. So, she and my son needed to travel to be with her.I agreed…2 days later, I was scrolling through Facebook and was shocked to see a video posted by her mom: my son and daughter-in-law celebrating their anniversary with 20 guests.

Furious, I took her son and put him in the car. Without thinking it through, I drove him to the nearest hospital and made him get a routine checkup. After all, a checkup is good for a child—and he even got a lollipop in the end, so he was happy.At the hospital, I took a photo of him and sent it to my son and daughter-in-law with a message that said, “Just so you know, we’re at the hospital!” Then I turned off my phone so they wouldn’t be able to reach me.Within just a few hours, they took a plane and came rushing back. My daughter-in-law was visibly shaking as she asked if their son was okay. I smiled and told them he was perfectly fine—but I also made it clear that I will not tolerate being lied to again.In the end, I felt satisfied that I gave her a taste of her own medicine. She lied to me, so I lied to her. Maybe I went too far—but their betrayal was more than I could take.Was I wrong?
