Having repented of their murderous ways The Anti-Nephi-Lehies bury their weapons of war and refuse to take up arms to defend themselves against their enemies. (Read the story here.) As a result of their sacrifice, more than a thousand souls were converted to Christ.
After battling for days, I had enough of the plastic swords and the crying and fighting that came with them. Instead of just taking the swords away, S.A.M. and I decided to make it a "teaching moment." Initially, they weren't too excited about burying their swords, but they soon got into spirit of it.
Update: The boys super secrety plans (They think I don't know. Of course I know! Moms know everything!) to dig up the swords on Halloween have been thwarted by the family dog. She dug them up this morning and had her way with them. Buwahahahhhaaaaaaaa!
