I was also amazed at the kids who learnt so fast, when i said caught up they were in the classes normal for their age and communicating with the other kids without problems after 6 months. At the time i thought it may have something to do with them starting their education much earlier than the swiss kids. They'd started reading and writing at 5 in England where as the swiss kids start at seven. They where 7 and 9.

I speak fluent Swiss-german but i still have a slight English accent, could be that my interpretation of fluent differs from others. I teach early english through play and the kids never fail to amaze me, i wish such easy communication didn't dissapear with age.
