the people who always talks rudely and abuses are already carrying their trauma since their past. you have to understand them and see them as they are , dont think about their words too much. And you should not let them exploit you again through their words by not paying attention while they abuse you. warn them to not talk with you in that way again . try to talk and solve your problem directly with them.

and if you don't wanna have a talk with them...then?
