I've always thought that Europeans weren't as hung up on nudity as we are here in the west (NA)?
When I was a kid living in Germany it seemed every place we went to swim there were topless females roaming free. And as an older male I clearly remember Crete and other countries I visited being just as open to it. Even having nude beaches.
If I had seen her hanging out the window like that I would have shaken my head and laughed. Seems a bit foolish is all. Maybe that was part of the problem?
