I can understand how someone might feel like they don't like being referred to as a "good girl", since I myself had issues for a while that the terms "cute" and "adorable" meant that I wasn't seen as an adult. My thinking has changed, and I know that terms like that don't mean that I'm not seen as an adult, but that I'm doing something that possibly emphasizes my innocence in certain ways. And as far as "good girl" goes, I like knowing that I'm pleasing my Master, no matter the terms he uses to tell me.
