Mandarin Bus

The other day I was on a bus to Tel Aviv (buses are interesting places). Sitting next to me was an earnest young man with a fancy beard reading one of our least serious newspapers, that is handed out for free at places like bus stations. He was reading his rag sheet, I was deciphering my daf yomi, until suddenly his cellphone rang, and he launched into an animated conversation in... Mandarin Chinese (Believe me, that's what it was. I wasn't certain, so I asked him, after the conversation was over. "Funny", I told him, you don't look Chinese").
