Ultural stereotypes in communication between Bulgarian and Norwegian children

The topic is specific. Children are between 10 and 12.
They communicate in English. Even they dont use the language fluently, they understand each other.
First BG students go to Norway, then the Norwegians pay the visit back.A survey has been completed.They communicated easily. Learned a lot about the other culture.
If you need any further information ,just let me know. Best, Elisaveta
