I have 4 kids and the 2 older ones have cell phone. One is 17 and other is 13. They walk to kids and is always gone. He said since they have been acting up in school I should get rid of their cell phone and I did. My sister said that was not a good idea because now I don't know where they are when school is out. She said I should have dealt with that another way. I want to keep the peace in the house so I did what he told me to do. Now I have no idea where they are when they leave. Was that a bad idea?
