Balec, mud and last piece.

1. I find Alec tapping away at a two-player game.* He says: 'I'm playing with my imaginary friend, Balec.'
Balec is losing badly so I play a couple of rounds to boost his morale.

2. Three small boys (none of them mine) stamping in the muddiest puddle in the entire park.

3. While I am making supper I remember that there is one last piece of millionaire's shortbread in the fridge. I eat it quickly while no-one is looking.

* Pettson's Inventions Deluxe is hugely popular here at the moment.
