We have taken many classes and continue to be life-long learners. The most important thing when asking a question to me is the tone of the voice of the Instructor and having the Instructor pay attention while I am asking a question and answering. This applies to answering e-mails or posting discussion questions too. I avoid keying in All Capitals or using the Exclamation point. I sometimes use the Exclamation point if I respond to a statement like "Very Good!" If I was in a live class, then I am enthusiastic when replying even if the question was not the correct one.
