Mashi, that must be a Continental Europe thing, with the variety of yogurt ... We have TONS of different kinds here too - of course I LOVE yogurt so it really suits me, but I can see that it's a bit crazy.
Reminds me of a foreign friend of dh's. He came over to visit a few years ago and on the day he was to get on a train for Paris, he asked dh to take him to a grocery store so he could buy some yogurt for the journey. The variety was so vast he was unable to choose anything and left empty-handed ...
