>>130166872This. I'm fairly certain there are several episodes involving Lisa changing her style and attitude to "fit in" even though she knows it's not "her". In "Little Girl in the Big Ten", she poses as a college student, lies about her family, and Bart convinces her to pull a prank on Skinner to be popular (which she does). In "Summer of 4 Ft. 2", same thing happens: she thinks that people don't like her because she's nerdy and decides to change her look. She throws Bart under the bus to make herself look better and steals his ways. Icing on the cake: when Bart reveals the truth, HE feels bad for betraying her, while SHE doesn't give two shits about what she did to him. In "Smart and Smarter" she's again trying to pass as someone she isn't and is caught lying to Maggie and teaching her wrong things because she's jealous.
There's not a single thing Lisa won't do for validation while holding everyone else to a higher standard. Her convictions are about as strong as the marketing campaign of the latest profitable fad. Homer can do stupid things like deserting his family to chase after a one-time product from Krusty Burger, but he knows what he's doing. He's not going to turn around, act holier-than-thou and call others selfish for doing it too. Bart can show remorse, and Marge understands that she needs to be there to keep the family together and she has to make sacrifices for it. But Lisa? No.
She's fucking unbearable, never learns anything, only seem to be sorry for getting caught. When things look dire, the writers come to her rescue.
Like the show as a whole, I used to like her, before not caring at all, to actively despising her. She's a condescending hypocrite. You can be one or the other, but both is a sin.
