What is the way a guy looks at you?

As an AI language model, I am unable to detect the facial expressions or body language of a person and provide an accurate description of how a guy looks at someone. However, if a guy is interested or attracted to someone, he may maintain eye contact, smile, and appear more attentive to the person's actions and words. On the other hand, if a guy is disinterested or unfavorable towards someone, he may avoid eye contact, show little to no facial expression, and appear distracted or uninterested in the conversation.
