My sister’s MIL only liked two of her five grandchildren. My niece was the number one favorite. She could do no wrong with the grandmother and grandfather. They took her on exotic trips like Jamaica and Hawai’i. They bought her Halloween presents and just because presents. They bought expensive and over the top Christmas and Easter presents.
This caused a lot of difficulty because my niece did have a big brother. They did almost nothing for him. He’d get a book for Christmas. Granted he liked books, but when you compare what she would get to a book… it wasn’t equitable at all. (Not that I think you have to match dollar for dollar, because the thought that counts and all that but when the kids are 4 and 9, you kind of have to at least seem balanced). They wouldn’t get him the other types of presents.
And to make matters worse, ex-BIL would give the presents to the daughter despite the fact that there wasn’t a present for the son. So my parents were frequently finding themselves making up for Lou and Papa Doc (is it at all weird that his favored grandfather name is the same one that a Haitian dictator whose regime supported state-sponsored terrorism used?). The whole thing was just ridiculous.
