I have a friend who nannies for a wealthy family here down in Sussex. They are quite posh but she gets on well with them. They treat her nicely and they think she does a great job with their baby daughter. She is a live-in nanny and is quite happy there.
The family recently had a dinner party prepared and cooked by mum boss, invited about 8 of their friends, the dinner party went on from about 7pm - shortly after midnight but the parents didn't invite friend to join them so she skulked around in her room and the living room all night alone. She wasn't on duty and the baby was put to bed before the guests arrived. I'm a bit miffed on my friends behalf that she wasn't asked to join in.
