'my departure to the Netherlands where I loved and worked for a while as an au pair girl on Zeist.'

That's funny. I was born and raised (and lived a great part of my life) there.
Surely you'll remember the main shopping street 'Slotlaan', and maybe the big castle 'Het Slot'.
Anyway; there's no chance we could have ran into eachother, because at that time I myself was living in France.
What a coincidence ...
