Tact and Politeness

Guy walks in on a woman taking a shower. "Excuse me, Madam", he says, being polite. "Excuse me, Sir", if he is tactful. Yes, I watched my first Truffaut the other day, the film being "Baisers Voles". I would love to watch the whole "Antoine Doinel" series. When will the "nouvelle vague" reach Hollywood or Bollywood?
