As you know I enjoy studying German. I intend to be able to speak sehr gut at some point. I like to collect older pedagogical books, because of the amusing approaches. Here is a sentence from a conversational-approach book.
"Yes, sir; we call that "ein Trinkgeld" in German, and Americans usually give good tips. Americans are always liberal and noble."
Just an example of what was squandered by two world wars. Obviously the Germans don't hate us today, but what a waste.
"Liberal" of course doesn't imply leftie there.
