Asking someone for permission to use their first name reflects a sense of politeness and respect. This small act of consideration can establish a foundation of mutual respect and shared purpose. It shows that you value the other person's feelings and boundaries before making any assumptions about familiarity.
When someone allows you to address them by their first name, you create a more open and friendly atmosphere. This exchange fosters goodwill and strengthens the relationship, giving both parties an opportunity to connect on a deeper level. It's a simple yet effective way to enhance communication, as emphasized in Susan C. Young's book, "The Art of Communication."
