It's not just the accoutrements it's everything. Her behavior on social media, her nasty attitude at times, it's everything. I love me some Rih Rih but she doesn't seem happy at all. She's constantly doing the most and doesn't need to.Why is it childish?
Conforming to others' ideals about what is appropriate is not growth, that's being worn down.
Her house, her social media...not harming anyone else. Her choice. Period.
