My parents were attachés overseas and had to entertain A LOT. I was asked to be the greeter at the Swedish ambassador’s house one night. As I am half Swedish (But know no Swedish other than the basics) I thought it would be fun. Come that night, and I am saying hello and welcome to everyone including high dignitaries. I thought I was a hit because people would laugh and giggle. Apparently, I was saying Goodbye instead of Hello in Swedish the entire night as they walked in the door.
