Morning.
Drizzling here.
I was thinking about the Lion, the witch , and the wardrobe with a mirrored door and a cat. Not by C.S. Lewis. If the door was left slightly open the cat would sneakily put a paw round the door and try to bop the cat the other side. As soon as the children opened the door the cat would be in there as fast as a rocket. Strangely enough the cat would soon be disappointed that there wasn't another room in there let alone another world.
