Lets say you ask someone 元気, and they reply 元気, but their facial expression and body language says somethings wrong. In this scenario what would the Japanese equivalent be to asking "Are you sure?" or "Is something bothering you?"?
Also, someone told me Japanese speakers would respond in a less contextually generic way to things like this, with things like physical injury, romantic injury, etc. getting a different response. Is this true? And if so, could someone elaborate on it for me?
