Yes, I remember that years ago I had a co-worker named Sebastian, a somewhat rude and boorish person but that is not unusual in co-workers who tend to think only of themselves and their own interests, naturally. I do not wish to say something to or about him. Actually, we are not on speaking terms. Oh, was he from Argentina? I wasn't paying attention to that at the time. He just wasn't that important in my opinion, at least not to me.
