And it's not great - wondered for years why my sister had issues with me - I'm a pretty nice person. So today my mother said something (not going to be spesific as very outing) about my sister and an achievement that's pretty spectacular and it clicked to me I'm the golden child and my my sister can never please my mother and also on reflection this is being played out with the grandkids.
Not sure how to quite how to even start talking to my sister about it.
