Been a while since I saw her creepy fake smile/happy face.
One of the reasons I started to get freaked out back when I still watched her videos was the fake expressions. Fake smile, fake happiness, fake sadness... You can tell on a lot of her posts/videos that some of her expressions/reactions aren't genuine. Like she rehearsed it or recorded it multiple times before posting.
There was a post a while ago in which she was filming the mirror while talking to the poor cat (?) and then she acted all surprised like "oh, wow. Did you guys see how my hair looks? I didn't notice until just now! By golly!" or some crap like that... Right
We all know you're obsessed with yourself, no need to pretend, hun.
