My parents have a developed favorite grandchild and it’s becoming very transparent and really aggravating to the non-favorite. We treat both kids fairly; so it’s quite frustrating that they do not. What’s even more annoying is that they also had a favorite child (who wasn’t me). So, it’s an old wound that is even more painful since its happening to one of my kids. We all keep the peace and try to make the best of the situation; but it’s hard.
