There are two completely different ethnicities just in the immediate area where I live, both of whom talk in their own language in public places and get aisles of the supermarkets devoted to them. If you widen the net about five miles, you can pull in three or four more. So yes, you get used to living in the midst of babel on a daily basis.

I also grew up in a town with a high immigrant population. English speaking, it's true, but it does mean that differences in dialect are something that I've been conscious of all my life.

if you get caught up writing about the languages, pull a Tolkien -- make it an appendix and add it to your word count. :)

Excellent plan - that's another 50 words, even with just the few words I've scattered through the story so far.

And now I must stop procrastinating and go and write some of the thing. :-)
