She came in and took her coat off right away and sort of chucked it on the bed. She had on a green dress underneath. Then she sort of sat down sideways on the chair that went with the desk in the room and started jiggling her foot up and down. She crossed her legs and started jiggling this one foot up and down. She was very nervous, for a prostitute. She really was. I think it was because she was young as hell. She was around my age. I sat down in the big chair, next to her, and offered her a cigarette.
“I don’t smoke,” she said.
She had a tiny little wheeny-whiny voice. You could hardly hear her. She never said thank you, either, when you offered her something. She just didn’t know any better.
“Allow me to introduce myself. My name is Jim Steele,” I said.
“Ya got a watch on ya?” she said. She didn’t care what the hell my name was, naturally.
“Hey, how old are you, anyways?”
“Me? Twenty-two.”
“Like fun you are.”
It was a funny thing to say. It sounded like a real kid. You’d think a prostitute and all would say “Like hell you are” or “Cut the crap” instead of “Like fun you are.”
