If not...

I wonder what happens if exchange students can't get along.

I feel very lucky with my exchange partner. She's wonderful and we can communicate well.

Some of the girls in my group can hardly communicate with their partner.
And the same goes for my sister.
She has to bridge the gap between two completely different cultures and that between boy and girl.

It's almost as if the school assumes everyone can go along well, but we all know that even within the same culture and group there are enormous differences.

So I wonder what happens if the exchange student only uses the family to sleep and ignores his partner and walks with the boys. For instance.
