It might be that you offend them in some way: Maybe your beliefs and ethos just don't align with theirs. Maybe it's something you said that rubbed them the wrong way. Maybe it's subconscious and they don't like your laugh or the way your voice sounds when you talk.
Whatever it might be, there's only one way to beat these people, these - haters. By moving forward, persevering, and living your best life -being the best version of yourself that you can be.
That's what our protagonist has managed to achieve here. By living her best version of herself that she can be she has managed to stick it to someone who looked down on her.
