LINCOLN, Neb. (AP) — A Nebraska school principal has apologized for sending students home with a flier that advises those who are bullied to not tattle on their tormentors.

The Lincoln Journal Star says some parents of fifth-graders at Zeman Elementary complained and posted angry comments on Facebook.

Zeman principal Donna Williams apologized directly to the families on Wednesday, and the district posted the apology on its Facebook page.

Among other things, the flier says telling on the bully makes the bully want to retaliate. And the flier asks, "Would we keep our friends if we tattled on them?"

District student services director Russ Uhing says the LPS philosophy is: Ask the bully to stop. Walk away. If the bullying continues, tell a parent or teacher.
