Rude Expat Confession

Most expats know this feeling: You're at the airport terminal, waiting to board your flight to your home country. And you are slightly embarrassed about your fellow nationals. Worse, you pretend not to be one of them. Even worse, you've giving up pretending and know you're just like them. (Maybe this does not apply to Parisians, who are just cool, no matter where.) Today I had a similiar experience at home. I had invited two Finnish mothers and their children to our home (I wrote about them a few days ago, they had just recently moved to Berlin and I seem to have a soft spot for such people). I had baked a cake, set the table, the usual. But the two moms, generally friendly, were rather unintersted in me, and didnt really try to hide it (Finns dont waste their time on friendly small talk-people). When my husband came home, he got a quick "hello", and they continued their own conversation (Finns are very unfriendly to outsiders whom they dont know-people). The sad part: I know these are my own "natural" characteristics. Many a friend may have found me cold and bored when they first met me. It takes me a long time to warm up to new people. I can be cold to "aquaintances" whom I dont consider "friends". Would my anthropologist have a term for this?
