You are sun

"Do you see that big ball of light, Kris?" Delila asked.
Kris nodded. He always nodded. He never ever said anything. Always nodding or shaking his head. He perplexed Delila with his odd manners.
"It's called the sun. Did you know that?"
Kris shook his head.
"Do you like it, Kris?"
He nodded.
"Can you say, 'sun'?"
He shook his head.
"Do you know what your name is?"
He nodded.
"What is it?"
No answer. Kris stared out across the picturesque landscape at the flaming golden ball of light.
"Is your name Delila?"
Kris shook his head, smiling. He pointed to his sister. That was her name, didn't she know?
"Is it Aunt Joey?"
Kris's grin grew wider, showing his handsome crooked teeth, but he shook his head again.
"Is your name Uncle Harrison?"
Kris threw back his head in silent laughter. She was just teasing him, and he loved it. Delila smiled too.
"Is your name Kris?"
Kris jumped and clapped his hands. He hugged her. She got his name right! He was elated. But he knew that she knew it all along. It was just a game she had made up. He thought she did it to make him laugh. He liked to laugh.
"Why don't you ever talk, Kris?"
He shrugged and shook his head. He didn't look at her. He looked at the sun.
"Why do you like the sun?" Delila tried so hard to make him talk. Sometimes she thought he could speak and was just hiding it. She would ask him questions so maybe he would forget that he did not want to speak. Maybe, if she asked him enough questions, it would make him want to answer her.
Kris pointed at the sun. Delila looked where he was pointing.
"Yes, I see. What is that, Kris, can you tell me?"
He pointed to her.
"Me. I'm Delila. You know that!"
He pointed at the sun again.
"That's the sun."
He pointed to her.
"That's me. What are you doing? You know all this." Delila was washed in a wave of distress. "What are you trying to say? Oh Kris! Please talk! Please talk to me!" Delila wailed. She fell on her knees imploring him to speak.
Kris smiled down at her, his cozy green eyes sparkled in his sky of freckles. He took her round face in his cold hands.
"You are sun."
