For those of us old enough, there is the shoe phone from Get Smart.
To counter this the school needs adopt a “No Shoes Policy” which is easy to monitor and enforce.
But from another old 60’s movie, “The President’s Analyst”, there is the phone implanted in everyone’s ear shortly after birth. Give up, oomis1105, The Phone Company rules!!!
Even an “average” boy by the time he has turned 12 has read enough spy novels to be able to stash a cell phone out of reach of the most nosy Principal, Headmaster, or Menahel.
The “phone” he leaves in the pocket to be confiscated is actually a bugging device which he will then use to listen in on conversations in the administrator’s office!!!
LOL! I love “Get Smart.” -77
