You put your right leg in

Just as we left the house to go shopping I noticed a scrumpled-up piece of paper on the hall floor, and rather than sensibly picking it up at the time I left it where it was to deal with it on our return. As the return involved carrying in armfuls of shopping I walked past the piece of paper and opened the kitchen door to put said shopping on the table.

"Don't let the dogs out, mum, there's a fiver on the hall floor" says Boy.

Not any more there wasn't. In the time it took Boy to say that short sentence the scrumpled piece of paper had vanished. Harry had a toy in his mouth so is probably innocent. All we can think of is that Piglet or Beattie's next poos will be expensive.

*kicks Ned for carelessness (dropping it)
*kicks self for untidiness (not picking it up when I first saw it)
*kicks Boy for stupidity (leaving it there, knowing what it was)
*kicks dogs for purposes of equality.
