Special is generally less useful than normal, and less rewarding in the long term. Special things demand attention for the wrong reasons, interrupting potentially good atmosphere with their awkward presence.
I think of my classroom as a laboratory in thought. In the classroom, I try not to have an audience, even as I might, in the case of a lecture, sometimes lead and direct the engagement with ideas. I really enjoy being a part of this collective exploration of thought, one that feels open-ended and exciting.
