Sepideh, who are those people? Aren't you, me, other italkers, and anyone on the earth those people? Or are they some aliens? Haven't we often judged each other soon on italki? It's all about a wrong deed, I better say an awful habit, we all suffer from to some extent. Plus, human being tends to focus on a person's negative features more than his positive features. So we all are prone to judge and be judged soon. 

My reaction: glad not to have wasted any time on you. 

I am thankful to people who make incorrect snap judgements about me because they have revealed their values and shallowness, so I don't have to do the work to find out whether they are worth befriending or not.
