The one think that I have learned (Often the hard way) is that my selfimage is protecte and preserved by the ability of being able to laugh at myself and to remember that we are outnumbered by the students. One is out there alone. Lets say you have 20 in a class and each one asks 5 questions (usually very close together). It is easy to get confused and like Lucy you relply, blank out or forget what question you have given a totally unrelated answer. Hey it can be a little face redding - don't take it to seriously your a human. Often the students can and will relate to that. None of them want to be up in front of the class. Many times later on you'll think that the whole thing makes a great story. Enjoy teaching and use your sense of humor as a survivor tool.
