Depends, but generally if you're just talking, you should give said person a few chances. There are exceptions, E.G. said person insulted a dead family member knowingly.
OK, SO I KNOW THIS PERSON THAT I'M PRACTICALLY SICK OF TALKING TO; AND SHE WAS JUST BEING A BRAT SO I TOLD HER TO STOP TALKING TO ME. SHE SAID TO PLEASE GIVE HER ONE MORE CHANCE, CUZ LIFE IS HARD FOR HER RN. WELL? SHOULD I GIVE HER ONE MORE CHANCE?
