There was such a rush about me: wing, and tangled spray, and colors upon colors and shades of colors that were not colors at all but shifts of white … - Theodore Sturgeon

When I got back to my office Tween was there. She rose from the foyer couch as I wheezed in off the ramp. I took one look at her and said, “Come inside.” She followed me through the inner door. I waved my hand over the infra-red plate and it closed. Then I put out my arms.
She bleated like a new-born lamb and flew to me. Her tears were scalding, and I don’t think human muscles are built for the wrenching those agonized sobs gave her. People should cry more. They ought to learn how to do it easily, like laughing or sweating. Crying piles up. In people like Tween, who do nothing if they can’t smile and make a habit-pattern of it, it really piles up.

He could tell you things that make your hair curl, lose you sleep, or things that make you laugh.” He looked up at her swiftly, and away. “Or cry.”
He kicked a pebble into the water and watched the sunlight break and break, and heal. “More than that. Suppose you had a friend there waiting for you anytime you wanted him, anyplace. He’d give you all he’s got or any part of it, whenever you wanted it. And even more, you could shut him up if you didn’t feel like listening.
