Lost game before the game even started.

So I had this Anivia who was ranting about how no one ganked her lane and then they blamed her, I assume she was talking about the last game she played before. I probably should have dodged, but I didn't think she would do anything. She told us she would mute us all and then afk farm, she dies once and says gg. Then I come to help her lane, me playing rengar jungle, ults and kills the enemy mid laner, then complains how I KS after she autoed him once. Then decides to afk. After that my bot lane opens bot and it has become 2v5 with just me and top. Greatest game ever. Anivia must have been super tilted, why would she have qued up for another game. I dont know what im trying to accomplish by posting this but im just really tilted after that game.
