You're joking, right?
Why would someone who speaks English, Chinese and German in addition to Vietnamese be willing to work for $100 a month doing anything--much less cook you weiner-snitzel chow-mein, bangers and mash for dinner and wash your knickers?
You're havin' a larf mate!
For a $100 a month, you can get a fine housekeeper. Why do you need to talk to her so much? She'll see what needs to be done. I just smile and grunt and give pantomime shows to ours--she gets it-and she's great.
That said, ha ha, pretty funny. You are quite the joker.

The price is a bit more than what we were paying our housekeeper for the same dutes, in China - she was with us for almost three years. On other posts, some have been suggesting the going prices are almost double this. :-(
As for languages, well, as you say, why would someone with four languages be working as a houseeper - glad you found, and enjoyed, the joke :-)
yes, i know one who speaks all these languages fluently + ancient Egyptian, and has a degree in bio engineering from MIT and an MBA from Oxford, on top of being a black belt with 6 dan in aikido.
She is 19 years old and works for 89.99$/month.
are you interested?
