I sat on the steps next to Peter and watched him play his new guitar. His left hand worked the strings(弦)1 his right hand played.
"Just in time for the school talent show next2 ," I said.
"Are you doing anything for the talent show, Jeremy?" Peter asked.
"No." I said. "If I were a little3 , like you, 14 years old, maybe I could, too. I believe you'll win the first prize this year."
"Maybe." said Peter, "I'm playing a song I4 myself."
"You write your own song?" I asked.
"It's not5 ," he said, "My song is called Two for One, I got the6 easily from a two-for-one sale store. And I liked the sound of Two for One.7 song goes like this: "Two for one. two for one. that's the way to have some fun", I haven't written all the words yet."

"I got9 when playing baseball yesterday," he said, "Now I can't be in the talent show next week." Peter and I10 each other worriedly. Then I had an idea.

Peter's eyes were11 and lively.
"It might work," he said.
I sat12 him on the top step.
"Where can I put my right hand while we13 ?"
"Put it on my shoulder," I told him." We're14 , aren't we?
Our song answered that question. We finished writing the words together15 .
"Two for one, one for two. see what two good friends can do!"
