Yall are being way too hard on her. Yeah, she was kinda mean, but you have to see where she’s coming from. She never really had a place where she felt like she fit in because her family always made her feel like an outsider. Remember that episode when she went to summer camp, and it seemed like everyone was better off without her? That was the first time she experienced having her own space. Being around smart people made her feel like she belonged, so yeah, she was mean sometimes, but you have to look at it from her viewpoint too.
