My mom was against my doll hobby the most out of the entire family. Every day, she'd tell me what a waste of money they were. Amusingly, she'd occasionally ask me to bring out my dolls for her to sew for, but the cycle pretty much continued. This went on for about two years into the hobby.
Then, I bought her a 60cm Obitsu Gretel for Mother's Day because she was always complaining about how I only bought boys, how hard it was to slip their enormous hands through the sleeves, and how annoying it was to sew sleeves for 1/6th scale dolls.
After she got the doll, she completely stopped telling me the dolls were a waste of money. Instead, she tells me that I "have enough already" and that I should stop buying more. I'm so evil.
