I walked in to switch off Kai's air conditioner this morning, and I saw this. A piece of puzzle wedged, up high, between the a/c and the wall.
Terence got creative and solved the problem of the rattling plastic a/c cover, which rattles like a motor engine when the a/c is on, using one of Kai's puzzle pieces.
Kai's reaction? "Mummy, but I don't like it up there."
Well, darling, if a piece of the puzzle fits, use it.
