Yeah, I dunno. I don't want to focus on a bad experience I had. It was just surprising to be coming from a native English speaker because all the others from his country I'd met during prior travels had been the *most* laid back people in the hostel, etc.
I was supposed to room with this guy for two weeks (it turned into six) and when I was taken to the apartment he'd arrived in a few hours earlier, he refused to shake my hand and I got a very bad vibe. I should have trusted my instincts, but I actually couldn't believe my own feelings since it was the first time I'd ever felt hate directed at me. He verbally confirmed my first impression several times and I tried to blow it off. Denial, denial, denial.
Lesson learned: what people say is important.
Over the years in China, I met a few others from his land that obviously felt the same way about people like me, although I wasn't living with them. I've extrapolated from my experiences that this is a recurring proclivity for people in his country, so blah, blah, blah.
Let's just say that now I know, to some extent, how a Japanese might feel living in China.
