But also there's my waist , and my bust , and my calves . The negative : now people really know that I'm fat ( as if they didn't before . ) The positive : now they know what my fat really looks like , and that I don't expect them to be scared of it or repulsed by it . This isn't meant to be a fat manifesto ; I don't speak for all fat people's experiences because I can't . 
Question: What's a possible reason people now really know the writer is fat ?
Because the writer posted a photo of themselves .
