At virginia tech, students and professors remember the courage of professor liviu librescu, who died protecting his students from a gunman in 2007.

This story could show the Hero element of a culture. Liviu Librescu's act is considered to be good. It is also a story that teaches people how to act or what they deem as the "perfect" behavior. In this case, a teacher must always protect their students. Or an adult should always protect a child.
