What if I am cold to my bf's friend?
That's mean. Why would you be cold to your bf's friend.
I don't like the norwegian people. They are egotistical
It's rude to be mean to your bf's friend. That could hurt your bf's feelings.
This is true, well I think he knows I don't like Norwegians well so I don't care. My boyfriend doesn't care anyway.
Your boyfriend my not care, at least at first but eventually he might if you spend time together. It will be an uncomfortable situation to sit in silence.
