argh yes!!! thats the one I always cringe at using.
I cant for the heck of me use that 'xiao' word for those old men
I talk or write emails to.
we can't use that to address people older than us ... that's
more for peers ..
and one thing to note .. never address a woman in china as "小姐"
.. to them, a "小姐" is one who works in nightclubs/pros ...
