@stavvers reminds me of a joke: The six-year-old sits at dinner, grumpily speaking their first words ever: "Soup's cold." The family is thrilled: "OMG so you *can* talk? Why didn't you all the time??" - "Nothing to talk about."
@stavvers someone from Lower Bavaria once told this story to illustrate a certain tight-lipped grumpyness in their folk, so of course everybody actually speaks Bavarian. I guess if you can imagine that it will certainly add some flavour!
