The family wasn’t satisfied in the great Nanny they had (you!) & assumed the grass was greener.
They did all this w/out any concern about you.
This was callous, inconsiderate + overall disloyal in my book.
So they let you go, under the premise that they would get their unicorn Nanny overnight.
Well karma kicked in (as it usually does) and now they realized that you truly were a gem and that finding someone like you was not so simple!
Oh well.
Not your problem!!
Do not return to this position!!
They will try to screw you over again - trust me!
Look at them now, they won’t even write you a reference letter unless you return!!
Such shady characters!
I wouldn’t want to work for the enemy.
Stay where you are right now and do not look back.
Good luck!
