What is he looks at me while talking to someone else?

When someone looks at you while talking to someone else, it could mean different things. One possible reason is that they might be including you in the conversation or want to gauge your reaction to what is being said. They could also be seeking your validation or approval of what they are saying. In some cases, they might be multitasking or trying to manage a group conversation, and looking at you becomes a way to maintain eye contact with everyone involved. However, it's important to note that without additional context or information, it's difficult to accurately interpret someone's behavior.
