Absolutely. My grandmother has a favorite of her 4, and she has passed down that lovely quality to my mother. I was the favorite for a while because I met the ridiculously high standards. My other two sisters have not, and my mom used to adore me for that. Since I've "distanced myself from her" (mom's words) because I am no longer fitting her standards (meaning I don't "need" her like the others claim to), my mom is starting to write me off. She very openly gushes about my middle sister & her kids and acts as if they are so amazing. It's quite sad actually because this is the same behavior she used to do to this sister except she made her feel bad because it was always about me. I'm glad my sister is receiving the "awe" from my mom because she spent her childhood feeling slighted (and rightly so). However, it drives me crazy that this arrangement even exists at all.
Initially, I thought I was jealous because my sister was now receiving the praise and I wasn't; however, I've come to realize that it's not jealousy. Instead, it's disgust. Disgust because my mom picks and chooses us based upon HER standards rather than loving each of us for who we are. My mother still laments and gets angry when her mother openly chooses favorites and slights her, but she cannot see that she is perpetuating the same behavior.
For years my sister and I resented each other, and it wasn't until we both moved away from my mother that we realized that all the issues were caused by my mom and how she viewed us. I'm so thankful that my sister and I have cultivated a relationship despite years of being pitted against one another. We are now trying to not be this way to our own children - it's taken me 2 years of counseling to reassess myself, my parenting, and the warped relationship I had/have with my mother in order to break this cycle.
