Cable TV

When colored TV came out years ago, we looked forward to getting one.  The TV came "cable ready."  That was something new.  The kids were jumping with anticipation.  They can now see shows clear and in color.  After it was delivered I was reading the directions and there was a switch you could flip to lock stations out that I don't want the kids to watch.  Good, I can lock out HBO and some of those channels.  I put the book away and never showed it to the kids.  Little did I know that whenever I went out they played with all the switches and buttons to see what they did.  I came home one day and they switched the channel as I came in the room.  Okay, what were you watching?  Just a different cartoon.  Why I believed them I don't know.  This seemed to happen quite often.  Then I started to find the switch was flipped.  Caught like rats!  I caught them one day with HBO on and they told me they knew about the switch.  Punishment time.  No TV for the day.  Yes, this works but now they will be watching whatever they want when I leave.......
