Emily said to Rob that they looked nice and offered to try them on.
The shopassistant asked how he felt.
Rob answered that (видимо, речь идёт о туфлях?)the shoes were too small.
But the shopassistant insisted that they were Rob*s size.
Rob asked what was wrong with his feet and wondered if they had grown in a week.
Emily told Rob not to panic and said she knew what it was.
