I DID IT
Last weekend I visited the South of France. I tried my French and what was very pleasant to me, I was able to communicate in shops, restaurants. Of course, you are in stress and do not have enough words, but then you just relax and speak as you can. Nobody knows you anyway :) The most difficult was to ask to continue our conversation in French, as many people were switching to English and kindly asking maybe this would be more easy :). Mais, non, je voudre parler en Francais, s.v.p :).
