* Distraction: They might be watching TV casually, but their primary focus is on something else. They might be reading, working, or having a conversation while using the TV as background noise.
* Avoiding Eye Contact: Maybe they're shy or uncomfortable with the person they're with and are using the TV as a way to avoid direct interaction.
* Peripheral Vision: Some people have better peripheral vision than others. They might be able to catch glimpses of the TV even if they aren't looking directly at it.
* Subconscious Observation: They might be subconsciously monitoring the TV for something specific, like a particular scene, a character, or a news update, without wanting to fully engage with the content.
* Habit: They might have a habit of watching TV in this way, perhaps because they've always done so or it's simply how they prefer to watch.
It's important to remember that everyone has their own reasons for doing things, and there's no single "right" answer. If you're curious about someone's behavior, the best thing to do is to ask them directly. They might be happy to explain their reasons.
