No, Charles, I didn't say I was Ok with lying if they only believed it for an hour. It's better, that's all, than their believing it for a day or more.
The playing field thing is unlikely to be traumatic I agree. But then it's so underwhelming as a topic as to be pointless.
That's not the only issue though as I said, and many others have said. If you lie to children about something like that, first off you have to actually le - in a believable way - which is actually fairly difficult to do unless you really go for it, and I don't think that's very good for the soul.
Secondly, they will then be told you lied. Lying is something that shouldn't be encouraged in children, because a lot of them tend to try it out anyway, and to be shown by your actions that it is acceptable sends a very confusing message to them.
It is the sort of thing that would never engender respect for teachers in my eyes - because I knew lying was wrong, I would think less of them for 'having' to resort to it in order to teach us stuff. Pointless.
And then you have the whole thing about crying wolf, too. One day you're lying about the playing fields or - say for an example - wielding a fake gun while a member of staff gets shoved in a car and driven away in full view. (yes true story)
The next day there's an actual fire in the building, and the children don't believe you.
Bit short sighted? How are they going to know what's genuine - and surely the first thing you would do in a real incident of that severity (the gun thing) is a full lockdown, closing windows and sounding the alarm intermittently and calling the police.
I don't think that happened. What exactly are they being taught?
