Ask if Brussels is in Germany.
Be completely oblivious of geography, history, and politics. Ignore the fact that it’s actually the capital of a country quite commonly referred to as “Belgium,” which declared its independence in 1830. Remind us that, indeed, not so long ago zie Germans did wander around within our country’s borders for a lengthy period of time.
Because we share borders with countries such as the Netherlands, Luxembourg, Germany, and France, it’s of course more than likely that we are actually merely a province.
