at the desk didn’t even lift her eyes from the book. Mum pointed at a big chair
by the door and I knew she wanted me to sit down. While I watched, mouth open in
surprise, Mum took off her hat and coat and gave them to me to hold. She walked

I watched until she was out of sight and the nurse had turned back to writing in the big book. After a long time Mum came back. Her eyes were shining.
