I think what he is tryin to say .. let me give u a exampe of mine...
When i was little girl, I was soo invovled with deaf culture, its a deaf world to me..it was just my life about that. Deaf friends, ONLY..no hearing, and having fun and I lived in Phx. But til I was 8 I moved to CG where there were no deaf, or deaf school or anythin like deaf community .. it was a new world and a new life for me, I went to hearing, more talking, got CI..losing my deaf life, friends and the world. I disappeared that world cuz of my mom...then appear a new world of hearin cuz of my mom .. But I wish I could disappear the hearing world..to be into TWO worlds into ONE world=Deaf + Hearing = One World. Its what that quote is tryin to ask .. I think so, hope it clears you good and hope my story helps. G'day!
