"It's Tuesday night; bin night!" quoth the bot.
"We'd better put the bin out." remarks barakta.
"I've got the bin, you get the door. There isn't anything festering in the fridge is there?" says Kim, emptying the kitchen bin like a boss.
"Actually, pass me that recycling, I'll put it in the recycling bin while I'm at it.", going for extra credit.
And so it came to pass, and we hobble retire upstairs satisfied with a job well done.

"What's that noise?" wonders Kim, "Ah, it's out neighbour and his idiotic collie putting their wheeliebin out. Fair enough."
"Hang on, we didn't actually put the wheeliebin out, did we?" asks barakta.
"Yes, that thought also occurred to me. Which is why I'm at this very moment instructing the computer to remind us when we next go downstairs."
"But we'll just ignore that because we already did the bins."
"I've also anticipated that problem, so I've told it to say 'actually put the bin out you idiot'."
(I'm reckoning there's a 50% chance of extra div points in the not too distant future...)
