What is what does it mean when you catch a guy staring at you and then quickly looks away?

When you catch a guy staring at you and he quickly looks away, it could indicate a few different things, depending on the context and circumstances:

1. Interest or Attraction: One common interpretation is that he might be interested in or attracted to you. The quick glance away could be a sign of shyness or a nervous reaction because he doesn't want you to notice that he was staring.

2. Curiosity: He might simply be curious about you or something you're doing. This doesn't necessarily indicate romantic interest; he might just find something about you intriguing at that moment.

3. Embarrassment or Awkwardness: If he realizes that he's been caught staring, he may look away quickly because he feels embarrassed or awkward.

4. Daydreaming or Lost in Thought: It's possible he was lost in thought and didn't even realize he was looking in your direction until he noticed you noticing him.

5. Recognizing You: He might be trying to figure out if he knows you from somewhere and looks away when he realizes you noticed his stare.

6. Social Cues: Sometimes people look away quickly as a social cue to indicate they didn’t mean to be impolite or intrusive.

It's important to consider the broader context and any other interactions you've had with this person to better understand his behavior. Body language, social settings, and past encounters can all provide additional insight.
