“I still don’t know why parents let their teenagers use their phones with no supervision!”
My kids had flip phones until they had real jobs, and that was after high school. The flip phones are now required, due to lack of pay phones, but nothing else beyond that is needed for kids.
(and they didn’t even bitch about it, since they know how rules are set in our household)
I miss those old flip phones as they protect the screen unlike today’s “smart phones”..
