Yvette on 48 Hours
http://www.cbsnews.com/video/watch/?id=7118769n&tag=contentMain;contentAux
Teenage girl and her date were gunned down. He died, she survived. The show is primarily her talking about it to the camera and while she had nothing to do with the crime other than being a victim, she suffers from survivor guilt. What struck me was the odd smile she wears throughout the narrative of this horrific shooting and the aftermath. What's up with that?

She is atypical in her expressions, but her emotions are real. What likely causes the oddness that you notice is the length of time since the crime. She has likely worked through things after all these years and feels differently than she did when this happened.
