What is what does it mean when a guy turns around to look at you?

Curiosity: He might be curious about you for reasons other than romantic interest. Perhaps you resemble someone he knows, or he's intrigued by your style or demeanor.
Checking for Familiarity: He might think he recognizes you from somewhere and is trying to place you.
Judging/Observing: Unfortunately, sometimes a glance isn't positive. He could be judging your appearance or eavesdropping on a conversation. This is less likely, but important to acknowledge.
Accidental: It could be purely coincidental. He might have been looking at something behind you and accidentally made eye contact. Or just glanced in your general direction.
Non-Verbal Communication: He is trying to start a <a href="https://www.wikiwhat.page/kavramlar/non-verbal%20communication">non-verbal communication</a> with you.
