'Anna!' It was my boss, David Amos, the owner of Amos Cosmetics. He happened to be walking past where I worked. He never usually spoke to people like me. What did he want? I felt nervous. 'Yes, Mr Amos.' I said. 'You're looking terrific today! Mmm . . . what's that lovely smell? It's like fresh bread and flowers and sunshine all mixed together with ... I don't know - is it you, Anna?' I didn't know what he was talking about. I couldn't smell anything special. Mr Amos had an expert nose for perfumes. And he knew it. 'Yes, it is you!' he said loudly. All the other chemists nearby could hear. It was embarrassing.
