I bought a simple little wooden theatre: you put huge sheets with pictures into the slot which in this photo shows the red curtain - and then I tell the story - with many comments from the audience.
The audience was taught to behave: they show their little entrance card, sit in a row in front of the theatre, and applaud loudly before the curtain raises.
A fairy tale as "The Frog King" is a bit diluted by the makers of the sheets - but "Nana" (that's me) does NOT let out the part of the King: "What you have promised, that you have to keep!"
Interesting: little children, though oh so sweet, can be quite cruel: the threesome cries out loudly that they think it utterly right that the princess throws the ugly frog against the wall when he insists on climbing into their little bed... "But the princess promised..."
Raucuous laughter: "We would throw him with gusto at the wall, yes, we would!!!"
Come to think of it: good so. A very clear attitude, no rotten compromise. :-)
