Basic , just be quiet and don't talk to them anymore. I have experienced talking to someone like this , I mean my family respects me and they never say anything bad about me and someone I know will just do it? its inappropriate and rude. My mother raise me right that's why I will behave when someone raise their voice at me. This kind of situation is kind of similar into gambling you can encounter some rude people but now I have realize that I can entertain myself without leaving home and still enjoy the day by playing on the best gambling site.
