Every human mind consists of a gaint perceptual world which is comparable to home!
Imagine three situations. Situation 1, we are visiting someones home just as a formality. There will be so many disturbances and diversions. We can compare this situation to casual hearing.
Situation 2, we are visiting someones home on a purpose. We might like some things at their home. We might enquire about few things. We might give them some gifts. This is comparable to normal conversation.
Situation 3, we are visiting someones home without any specific purpose, but we just want to spend some time. We might observe each and everything present in their home. We enjoy the visit just because it is interesting. We dont compare their home with our home. This is comparable to empathetic listening.
