I Dream of Small Grey Sheep

You may wonder about the small grey sheep. My screen saver is meant to be a 'magical Christmas scene' with LOADS of snow falling. But something has gone wrong and the falling snow just looks like grey sheep. It piles up at the bottom of the screen like a big sheep mountain-not very magical at all really.

'Happy Christmas, Wilf!' says Father Christmas and he turns to leave. 'I hope you get what you want!'
I panic. He can't go now, I have so many questions that need answering, questions like, 'how do you build an igloo big enough to fit an entire toy factory in?' and 'How do you manage to deliver billions of presents to billions of children in under 12 hours and where does Einstein fit into all that?'
But all I can manage is,
'Wait a mo! Where's your sack?'
He is quiet for a second and then he winks. 'Who needs a sack when you've got magic kiddo?'
And he waves a long, thin hand and white sparks appear all around him. They pop like bubbles and he is gone. Just like that. For a moment I cannot move. The room is back as it was, the tree, the lights, the cat licking her bottom. But nothing is normal, not now.
'I've just seen, Father Christmas, Serena. I'VE JUST SEEN FATHER CHRISTMAS!' Serena is disturbed mid-lick and stalks out of the room and I fly upstairs. I want to tell Mum and Dad, I want to tell Granpa Jack, I want to fling open my bedroom window and shout out the news! Father Christmas is alive! But Dad accidentally painted my window shut last summer so I have to just stare very hard out at the night sky, hoping for a glimpse of him.
'I've just seen, Father Christmas,' I say to Dexter, the computer.
'Does not com-pute,' says Dexter.
'Oh, yes it does,' I whisper.
And in my sleep, I dream of small, grey sheep falling from the sky.
