My parents lucked out with three boys (although we were far from angels). My high-school sweetheart came from a family with *six* girls (her dad kept trying for a son to no avail.) They were all hot as well! That poor father. I always wondered how he paid for weddings. He was older than his years.
"Shutdown: Several hours after activation, you may desire to shut down your teen-age daughter. There is no way to do this."
We learned to physically disconect the phone from the input source leading into the house at 9:00 pm. And NEVER EVER agree to a cell phone unless she pays for it. Our oldest NEEDED a cell phone. She had to wait until she was 18 and she paid for it. After the first bill, the cell phone ended.
P.S. Same with pagers
