Final answer:
The provided texts do not mention Gramps and his decision to wait before calling Sal's father. This is a scenario common in literature where characters hesitate to share distressing news.
Step-by-step explanation:
The referenced texts do not explicitly mention a character named Gramps who wants to wait before calling Sal's father while Grams is in the hospital. However, based on similar contexts in literature, it can be assumed that Gramps may have wanted to wait a few days before calling Sal's father to avoid causing immediate alarm or because he didn't want to worry Sal unnecessarily until he had more information about Grams' condition. This type of scenario is common where characters face dilemmas about delivering potentially distressing news to loved ones.
