What is he stares at me with a blank face?

When someone is staring at you with a blank face, it typically means they are not showing any emotion or expression. It could be a sign of confusion, disinterest, or they may not know how to react in the current situation. It is important to pay attention to other nonverbal cues such as body language and tone of voice to determine the meaning behind the blank face. It is also important to consider the context of the situation and any previous interactions with the person to gain a better understanding of their behavior.
