Isabel has a specific view on telephone etiquette that shapes her interactions. She believes calls before eight in the morning should only be reserved for emergencies, while those made between eight and nine are considered intrusive. This sets a clear boundary for her morning peace, illustrating her careful consideration of others' schedules and comfort.

Beyond nine in the morning, Isabel feels more at ease making calls, but she still recognizes the social dynamics at play, such as needing to apologize for calls made after nine-thirty. This framework reveals her structured approach to communication, ensuring she respects others' time while also navigating her own needs.
