Answer 3

why did you called me moron? Did I offended you?

I bet you don't call people on streets or your co-workers or anyone around you because you would be hit. But you came to your computer and be stupid with other people. Are you looking for a scapegoat? Do you need your pc to put your anger out?

I really didn't get it.

Perhaps I wrote something wrong, is that? If it is the point, at least I am learning one more language. Do you speak something else? I hope not.
