Final answer:
Arya misses the endearing nicknames, the care shown through inquiries about her life, support at her track meets, and the ongoing engagement her grandparents provided, which made her feel loved and valued.
Step-by-step explanation:
It seems like Arya misses several things that her grandparents used to do. From the descriptions given, Arya's grandparents had sweet nicknames for her which made her feel loved, they showed interest in her life by asking about her whereabouts and what she was wearing, they were present at all of her track meets demonstrating their support and care, and they engaged with her by making remarks and asking questions which likely made her feel valued and included in their lives. The mention of both track meets and concern for her clothes suggests an attention to both her accomplishments and her well-being, indicating they played a nurturing role in her life.
