I found ^that^ while looking for your quote: "Who can't hear gon' feel" -- but it didn't really explain the saying ... :(

Never~the~less ... I realize it ain't "Rocket Science" ... and it made me think of the deaf -- They may not be able to audibly HEAR, but they can FEEL the vibrations and hence, they can also DANCE to the music -- :)

~OR~

One may not be able to hear the crying or wailing of grief ... yet they can empathically feel the hurt, pain and/or disappointment of another's trauma.

*Good Word*
