My approach and experiences, continued...
I am open and explain certain decisions, e.g. why our children go to an international school and not to a local one, why I work, and why I haven’t taken a German language course yet.
I go to the local shops. Every day I go to the Migros around the corner, even if I don’t need anything 😉. As a result I have a little chat very regularly with the cashier. I speak German to him (well I try) and he tries to speak English back because he wants to improve it. It’s fun and informative; I know a lot more about traditions, upcoming events and (local) Swiss life.
Involve people in your own traditions. I asked the neighbours to be part of our Sinterklaas evening and in December we organised pre-Christmas drinks for the neighbourhood. We celebrated both in a Dutch way, with Dutch food. We had such a lot of fun.
