Well thank you for the advice. I appreciate it. And I agree with you. I always used to say, you learn something new every day. And you should strive to do that. New found knowledge can always be valuable. If not at that present time, sometime down the road. I think that this is not really a problem anymore. I must have taught that particular student something new and they lost that attitude totally. We'll see how the rest of the semester goes. Thanks again!
