if we are getting super-technical, it's pronounced "aysh," like in the word 'facial'
but back to the original thread before i hijacked it:
if you think you are the only person nervous about making a good impression, i've got news for you: you're not alone.
like i said before, relax, be yourself, be helpful, ask INSIGHTFUL questions, do NOT make your residents look bad, be prepared (have your white coat pockets overflowing with 4x4s, ABDs, tape, trauma shears), do NOT be obsequious, know your anatomy, go out for drinks (but try not to get too drunk - bad form), don't schtup the help while you're there (unless, of course, you're encouraged to do so by your residents), and remember that shampoo is better, because it goes on first and cleans the hair.
if peeing your pants is cool, consider me miles davis
