Even the word

"Earth. Even the word sounded strange to me now... unfamiliar. How long had I been gone? How long had I been back? Did it matter? I tried to find the rhythm of the world where I used to live. I followed the current. I was silent, attentive, I made a conscious effort to smile, nod, stand, and perform the millions of gestures that constitute life on earth. I studied these gestures until they became reflexes again. But I was haunted by the idea that I remembered her wrong, and somehow I was wrong about everything."
