Are girls getting meaner?

Tina Fey wrote the 2004 hit film “Mean Girls* after reading a “Queen Bees and Wannabees” by Rosalind Wiseman. It focuses on the ways in which teenage girls form cliques and how to deal with the sometimes aggressive behavior of high school girls. So, are girls getting meaner? WGN Morning News talked with Wiseman about this issue today because of the recent cyber-bullying that led to the suicide of a 12-year-old girl.
