No matter how much he talked, she never answered him, but he knew she was still there. He knew it was like the soldiers he had read about. They would have an arm or a leg blown off, and for days, even weeks after it happened, they could still feel the arm itching, the leg itching, the mother calling.
When someone you love dies, and you're not expecting it, you don't lose her all at once; you lose her in pieces over a long time - the way the mail stops coming, and her scent fades away from the pillows and even from the clothes in her closet and drawers. Gradually, you accumulate the parts of her that are gone. Just when the day comes - when there's a particular missing part that overwhelms you with the feeling that she's gone, forever - there comes another day, and another specifically missing part.
And now she was colder by the hour, more dead with every breath I took. I thought: That is the fear: I have lost something important, and I cannot find it, and I need it. It is fear like if someone lost his glasses and went to the glasses store and they told him the world run out of glasses and he would just have to do without.
