The term 'move about restlessly' can be summarized by two words: FIDGET and GAD. FIDGET is a verb meaning to move about restlessly, often due to nervousness or boredom. It is derived from the Middle English word 'fiken, ' which means to move quickly. GAD is a verb meaning to wander around aimlessly, often in search of something. It is derived from the Old English word 'gadan, ' which means to go. Both words describe the same action of moving about restlessly, but with different connotations.
