When I was in Tokyo last, I got in the elevator and there was one other guy in there with me. He asks me if I'm American and when I said yes, he grinned approvingly and enthusiastically said he, in fact, was South Korean. I was very confused as to why he thought that meant we had some kind of connection. He then asked if I wanted to come back to his room for a drink, which made me very uncomfortable because I just wasn't able to read the social cues well enough to understand his intentions. I politely said I was busy. I'm guessing he was just trying to be friendly, but I sorely wished I could just stare at my cell phone and not interact with him.

Both foreigners/travellers, perhaps?
