Ha! They've not lost all their past Finnishness then.
LOL! I gotta tell ya a cute story.
One of my close friends is Finnish and he has a beautiful sauna that we were using one evening, and after steaming ourselves we would go outside for a bit, drink some beer (gotta hydrate, ya know), then go back in for another round of steam.
At one point, his teenage daughter drove into the yard as we were outside and she walked towards us, and I panicked! I didn't know what to do because we were in da buff. So, I just took the cue from my friend and just stood there as she came and talked with us, but the thing that surprised me is that she didn't care one iota by all indications. I certainly wasn't used to that, so my sweat level definitely increased until she left.
