It was the Christmas when I was 15. I usually shared a bedroom with my sister, but she was staying with relatives, so I had my bedroom to myself. I went to bed last, and lay awake reading, my bedroom door closed. Lying there, I heard my brother walk from his room to the bathroom.
Then he walked from his room to the bathroom again -- only without first returning to his bedroom. After that he went up and down the stairs several times – sometimes without bothering to come back up before going down again. Sometimes he started down the stairs without having walked across the landing to get there.
I couldn’t believe her. She insisted that when the baby had cried, she had asked my Dad to fetch the powder, and he’d started to get out of bed – but then she’d found the powder, and Dad had lain down again. He’d never left his bed, let alone walked out of his room, along the landing and down the stairs.
