You start wondering who it was at the door. Suddenly, a head sticks in through the open window. No need to wonder anymore.
'Hey, can I have a gallon bag of sugar by any chance?' your friend asks.
'Yeah, sure. Just go over to the sugar factory and they'll give you some,' you say. 'Actually, there's some in the pantry. There's a lot of other things in the pantry too, so don't touch anything but the sugar. Got it? I've got explosives in there, and matches!'
'Ok.' your friend makes their way to the pantry. You wonder if they can be trusted with the explosives and matches.
