My mother thinks that my sister is someone else, I have corrected her a few times and she then recognizes my sister. On the other hand my sister just lets my Mom think she is a friend, I do not think that is good for either one. My sister gets aggravated at me when I suggest that she corrects Mom. My Mom seldom treated my sister lovingly when she was growing up (me either but I left at 15) So now my Mom treats her a little bit better, I guess my Sister doesn’t want to rock the boat. Opinions?
