Have always heard about how 'mean' girls can be to each other. When does this trait begin to emerge? Any ideas what causes it?
Did you experience it yourself growing up, and what were your strategies for dealing with it?
Were you the 'mean' girl? Why? What made you stop - or did you just grow out of it?
BTW - not talking about targeted bullying toward a specific child, just general unpleasant, dominant 'alpha female' traits...
