ok, so yesterday my friend was at my house, we were playing video games, and we sometimes joke around and call each other words like idiot, dumbass, and retard. my sister entered my room while we were playing and she heard him call me retarded and became furious. she beat the **** out of him and told him never to call me that again. my friend ran away crying and i sat there in shock. idk what to do now my friend is scared to come visit me now sometimes scared to be around me.
