Today I took a tram to sch. In the tram, this blonde who was reading a chi passage asked me if I spoke mandarin. Then she asked me how to read this word which turned out to be 'xu1' as in 'xu1 xin1'=humble. Then she asked is it "x?" then I was like "yup...x-u" hehe then she looked up the chi dictionary which she cldn't find in the dictionary initially as she skipped a page. Interesting stuff...=)
