I have two friends in Germany. One of which is my husband. He's away talking to other people about math in California. My other friend, well, I would like to keep her that way, so I'm not hounding her saying "let us in, let us in!" I've only showed up unannounced on her doorstep once, actually.
Disclaimer #2: I'm not a fan of taking them out in public either. They scream, people look, it's not fun. Maybe that's why I only have two friends??
