I'm an economist. Her brother is a mathematician. She regularly belittles my work saying " Math is much much harder. Only those who cannot cut it in Math turn to Economics ". Which is not true.
But she regularly brings it up and we argued about it for 2 hours. Why does she even care to argue about it for 2 hours. In my case Economics is my field and I have to defend my field. In her case she isn't a mathematician so why does she have to be so aggressive about attacking mine...
