Definitely eyes... آپ can tell something (practically everything) when آپ stare at someone's eyes. آپ can also tell if they're lying یا not. آپ can tell what they are feeling at the moment when آپ look right into their eyes. Unless you're clueless, of course...
The eyes, just because آپ can tell how someone feels یا what personality they have (sometimes, personality isn't always that easy to decode) just سے طرف کی looking into their eyes. Especially because when I see a person یا creature that makes me sad یا scared, it's almost always because of the look in their eyes.
