I don´t have anything to worry in general, I´m not letting anyone treat me like this, that´s it. And now he won´t get any reaction of me anymore, which is his own fault. Treat other players with respect and you won´t get ignored, simple as that. If you can´t fulfill this simple rule, don´t waste my time. Not willing to give mean-minded people any upset reaction for the sole purpose of their entertainment.
