Update:
My wish list was deemed to be reasonable, but they've now decided they want a housekeeper..... and their old nanny is returning as she hates her new employers (her words).
I really feel as though I've had a rough ride, considering I was told "We're not looking for another --" and "We don't expect you to do housekeeping duties"
To turn round and say, "Oh sorry, we didn't realise how much she did. We DO want a housekeeper, and you're not it"
Oh, people!
Now I have to look for a new job :-(
