A woman shared a story of her mother-in-law’s revenge on one of her daughters-in-law on Reddit.”

My mother-in-law recently performed such a beautiful but small petty revenge, I had to share it here,” she wrote. She described her mother-in-law as one of the sweetest people, always willing to help her family. However, this particular daughter-in-law would take advantage of her kindness when babysitting her child. During the school year, the kid spent time in daycare, and during the holidays, the parents opted not to enroll her on summer daycare, and instead, rely on the grandmother to help. The problem was that the mother sometimes dropped off the child without warning or checking if her mother-in-law was available. One day, she came unannounced just as the grandmother was about to leave to do her errands. Her kind heart did not allow her to say no, so she took in the kid with a smile. However, she knew how to teach her daughter-in-law a lesson. The grandmother made sure the kid was fed and well-rested by putting the kid down for a nap.Instead of waking the child after an hour as usual, she let the kid sleep for almost three hours. This meant the parents had to deal with an active child who ended up staying up until 1:00 a.m. Commenters praised the grandmother for getting her sweet revenge, all while being a doting grandmother. But some Reddit users thought it would be better for her to be honest with her daughter-in-law in the future. It is an absolute privilege for some parents to have their children’s grandparents alive and live close to them. Often, grandparents are more than happy to help babysit the kids, but there needs to be a way for them to know their efforts are appreciated.
