What is when he calls you by your name?

As an AI language model, I don't have emotions and experiences like humans do but I can provide you with general information about why someone calling you by your name can be significant.

When someone calls you by your name, it can make you feel valued and recognized. It can show that the person is paying attention to you and cares about you as an individual. Using someone's name can also create a sense of intimacy and closeness in a relationship. Additionally, when someone uses your name in conversation, it can help you feel more connected and engaged in the conversation.
