Final answer:
Cannot accurately determine the symbolism of 'clicking heels' for the character 'Papa George' without more context.
Step-by-step explanation:
The sound of clicking heels on the floor represents different things to different characters in literature. In the provided excerpts, clicking sounds are perceived in various sensory and psychological ways. For John, the sound is part of a nervously charged environment, possibly representing an intrusion or a disturbance in his space. However, the question asks specifically about 'Papa George' who is not mentioned in the excerpts given. Therefore, without context on 'Papa George' and without making assumptions, it is impossible to determine what the clicking heels symbolize for him. Hence, providing an answer to what the clicking heels represent to 'Papa George' without further context would not be appropriate.
The sound of clicking heels on the floor represents ghosts from the past to Papa George. In the provided text, the sound is described as coming from a vague figure standing by the door, which seems distorted like a reflection seen in a dirty pane of glass. This suggests that the sound reminds Papa George of past experiences or memories that may be haunting him.
