I used to be a nanny (pre having my own kiddies), and I often meet up with the family I nennied for. I to am not as great at keeping in touch as I would like, somehow real life and children get in the way and all of a sudden you realise that a whole 6mths have gone by just like that!!!
I would say that she is being completely honest and really does genuinly want to see how the kiddies are. When you have nannies for a family for some time, and maybe even lived in, those children become very much a part of you (and I KNOW how that feels). She probably really does just want to know how they all are, and also that they miss her as much as she misses them.
My old charges were a girl and her twin brothers who were not quite 5 and 2 when I started living with them and nannying. I fell in love with the whole family completely and utterly, to the point that when I had my first child I went back with her when she was just 5wks old to look after them part-time and holidays.....
They are all now 21 and nearly 18....and when I see the boys now (well, men really), I swell with pride that I had something to do with shaping them and .
The daughter even comes to sleep over occasionally, and she is a delight.
AND.......I only get to maybe see them evry few months, but we all understand how life goes. Just because we/they are out of sight, it doesn't mean we don't have them in our thought.
HTH some, and tell you friends, that she really does only want to see how they are all faring.
