I think I will now. You've convinced me! And I'm really curious. I've
got to be honest with you, everytime I'm in Bordeaux or Perigueux I get
draged to the markets by my old aunt, and she is really keen on the
local co-op. These are quite nice and they have Madeleines, and I'll do
anything for one of these now to dunk in my tea, right now too! Do you
know them?
