Zazu goo dluck. I live in an extreme small village (apparently 800 people in total, incl kids). So, when we moved here, we moved for the area, and decided that no matter what, we WILL make it work for us.
have been here now 2 years, and my child went to a private school at first - which was way to much driving in the end - and so this year, we have moved to the normal swiss school, and I am more in my own area, than to be on the road driving to and from schools.Anyway...I have always thought that my village are extreme Swiss, and meaning by that, the language...but now my child goes to normal school here, and so many of the moms have called up and asked if my child can come and play there, and when I struggle a bit with some of the words, are quick to say that they wish to speak English, and can speak it, but that they want to 'exercise' their english.
So, my point is...I have been pleasantly surprised as to how many people do understand english, BUT...you HAVE to show the effort to them that you are willing to try your german, that you are willing to give everything a try.
Move to the area that you wish, you will always find a new friend, always will find an english person, or even will find Swiss speaking people, that are willing to give you a chance and might even speak English after all, they are just to shy!...at best, you will have the EF always
good luck
