i finished school before the invention of the internet and mobile phones etc, so there was nothing to worry about, your aprents always knew wehre you were, because if they didn't, they'd give you some wallops when you got back
and the biggest thing to worry about was the 55 minutes you had to wait before monkee magic came on because you were too thick to reliase that 6.55 meant 5 to 7 and were sitting in front of the telly at 6
