What I will say is, yes I want the GM to have a conversation with the players and I want the GM to speak in an everyday voice, not put on an act. Obviously I am not going to be a jerk to a GM who does things the other way. And I am not going to ruin anyone's fun if the GM at the table decides to describe things in a literary way.
"A dialogue is a literary technique in which writers employ two or more characters to be engaged in conversation with one another. In literature, it is a conversational passage, or a spoken or written exchange of conversation in a group, or between two persons directed towards a particular subject."
What you do is literary, too.
