I didn’t know what to write next. I had no ideas.

I sat there for what must have been hours. The candle had left a mountain of dried wax at its base, was barely an inch left.

There came a knock at the door. I ignored it at first, still thinking about what I was going to write, but it was insistent, wanting to get in but unable to because I had blocked the door with the brick.

‘Hello? Is anyone in there? I need help, it’s so cold out here and I haven’t got anywhere to stay.’

I smiled as the first idea came to me.

‘Hello,’ I said, beaming as I opened the door.
