In the first place why did she buy them Iphones?
Growing up in another era where all you had were land lines we didn’t feel the need for such methods of communication. And we were limited to the in use the home phone time.
Parents had to know where we were going and when we’d be back and a phone number to call. Unless all we were doing was bike riding or roller skating up and down our block.
Dad or mom controlled the TV. We just turned the channels for them.
I often wonder about that. Almost every parent I know insists that his/her child "needs" a smart-phone.
