My Aunt Bessie was deaf form birth. Never saw any indication she could hear anything at all. One day we are down in the basement rocking out. Aunt Bessie comes down, huge smile on her face, goes straight to one of the JBLs and puts her hands on it. Big smile, rocking her head, she is practically hugging it. Just like this guy in the video.
She had been over before but never come down in the basement. Parents were out, we figured we can rock out, Aunt Bessie won't mind, she is deaf. Never imagined she would feel the vibrations through the floor, want to come down and enjoy the music with us. But she sure did.
Wish I had known the balloon trick. That would have been beautiful.
