Why would a guy stare at a girl's face so intently?
What kind of body language should a guy be looking for in a girl's face?
A guy might look for subtle facial expressions, like a smile or a frown, to gauge how the girl is feeling. He might also look for changes in the girl's eyes, like dilation or squinting, which can indicate interest or discomfort. There are many different cues that a person can pick up on from someone's face.
