I thought for a moment. "Well, perhaps the beginning – of your world, I mean – would be a good place to start."
Tim settled more comfortably into his pillow, and looked at me expectantly.
"When we arrived," I began, "everything was dark – I'd never been anywhere without light before, it was really strange.
"Then suddenly there was light again – so bright it was dazzling. We moved a little closer, and I couldn't help giving a gasp of wonder. Against the blackness, like a jewel on velvet, hung a blue-green ball, spinning slowly."
I paused. "I knew even then that it would be a wonderful place. I drew closer again, and I could feel the air beginning to tease my wings. I let myself fall, the air slowing me, then I glided, the moist air cool against my face."
I smiled, remembering. "When I landed, there was already grass, and the trees were in full leaf. I heard the rushing of wings, and looked up, astonished by the sky full of so many kinds of birds. I was tempted to join them, then I felt the ground shake as a huge herd of animals – buffalo, I think – rushed past.
"The stars were coming out, and I watched them for a while, amusing myself seeing shapes in the constellations. Then something remarkable; a glow on the horizon, then a huge orb rising. I watched open-mouthed as the landscape was drenched in a silvery light, each blade of grass distinct.
"I heard the sound of singing begin, and I added my voice, as my sheer joy in this new world overwhelmed me."
I looked across at Tim, and he nodded sleepily. I smiled, and dimmed the glow in the room to let him rest.
When the first light of dawn filtered in through the window, Tim opened his eyes.
"I really enjoyed last night," he said.
I nodded. "There's more to tell – maybe tonight we can carry on. But don't you have to be at work today?"
He nodded, sitting up reluctantly. "Give me a minute..."
I smiled, and got to my feet, going out of the door and downstairs.
After a few minutes, Tim came down, dressed, his hair damp from the shower, looking more awake. He poured a bowl of cereal, and I listened to the crackling as he ate.
"Are you coming with me today?" he asked.
I nodded. "Just in case of earthquakes, careless drivers, falling jumbo jets, the usual."
Tim grinned, finishing his cereal. "Actually, it's very reassuring."
He got up from the table. "I'll get going then. If the day's uneventful, I'll see you back here."
I watched him get into the car, then as he drove off I followed in the normal way. As Tim sat down at his desk, I was already in my chosen corner, and I watched as he checked email, went through papers, drank his first coffee of the day.
A few minutes later he got up and went through to the outer office. I quickly walked to his desk, and picked up the pen he'd been using, putting it back in the desk drawer. Tim returned, and as he sat down I saw him frown in puzzlement, looking round his desk and lifting his papers to check under them. He opened one drawer, then another, retrieving his pen.
He looked up, and spoke into the empty air. "Very funny – thought you were supposed to be keeping me out of trouble, not causing mischief."
From the outer office I heard the voice of his secretary. "Did you say something, Mr Smith?"
"No," called Tim. "Just muttering to myself about this last email from Marshall."
I let myself fade into visibility for a moment, grinning, then faded out again.
Tim rolled his eyes. "Now I know where Lewis Carroll got the Cheshire Cat from."
The rest of the day passed without incident – I watched Tim eat his lunchtime sandwich, wondering if I'd like ham salad – and I followed Tim home, letting him find me as usual in the kitchen.
He came in grinning broadly. "Actually I quite like knowing you're there – I don't really mind the odd trick."
He sat down opposite me. "How about I take you out for dinner?"
I smiled. "I'd like that."
"I'll go and change," he said. He paused. "We'll be going somewhere fairly formal – do you, ah, think your dress could be a little longer?"
I raised my eyebrows. "I'll see what I can do." While he was upstairs, I reached out my senses to the colour supplement of the newspaper Tim had bought on the way back from the office, viewing the pictures in my mind.
When Tim returned, I was standing in the living room, and I smiled, turning slowly. "What do you think?"
He blinked. "Wow – that's a more dramatic change than I expected."
I'd kept the feathery quality of my dress, but the style was now off the shoulder, and the hem swept around my ankles.
"Gorgeous," he pronounced. We walked out to the car, and as usual he held the door for me.
We set off, and after a few minutes Tim pointed to lights in the distance. "There's the restaurant."
We pulled into the car park, and walked towards the lighted doorway. The maitre'd approached, and we were quickly seated.
Tim turned to me. "Would it be all right if I ordered champagne for us?"
I smiled. "Something new again – I'd like that."
