What is he stares into my eyes without smiling?

When someone stares into your eyes without smiling, it can give off a sense of intensity or even suspicion. It could signify that they are trying to read your emotions or intentions, or perhaps they are deeply focused on what you are saying or doing. However, without a smile, it's harder to discern if their intent is positive or negative. It's important to consider the context of the situation and the relationship you have with the person to understand why they are staring without a smile.
