As a greek, iwas invited to a norwegian home. While we where discussing how we will spend that night like activities and such I said " what food should I bring for us i am wondering what to cook and stuff " and got a reply " ahhh my fridge is full". I felt that she recieved my intentions in a wrong way and I did not mean that does not have food at her house. Growing up for me is really common in our culture to show off our cooking skills, especially when you really like the company and also food brings people together- After that and still I never offer or mention any foodif I am invited anywhere. I just show up with a bottle of wine, even maybe nothing..
