Yesterday morning Mrs.C told me that I'd been talking in my sleep during the previous night. Always a bit worrying when she says this but I went with the flow... "So, er, what was I saying?"
"I have no idea, you were speaking German".
Which is all well and good but beyond ein, zwie, drei and danke/bitte, I don't speak German at all. But apparently I was there rabbiting on in what sounded like full on fluent jabber.
