"Shush!!"

I have a middle school class every Monday, Wednesday and Friday. The class has 3 boys and 3 girls. The girls are sweet, shy, quiet and smart. The boys are loud, uninterested, funny and incredibly annoying.
There is one student in particular, Jerry, who is always getting in trouble for talking in class. I know that sounds crazy being an English class and all, but he's rarely on task and almost never talking about the subject the rest of us are discussing. I'm constantly saying, "Jerry, be quiet." "Jerry, shuuussh!" "Jerry, seriously, shut up." Yes, I've told my students to shut up. You can't do that in the States. At least not that I remember.
Today my students were asking me what kind of job I had before I came to Korea. I told them I used to be a journalist. They said, "Oh, like a reporter?"
"Yes," I replied. "Like a reporter."
Then they asked me if I'd ever written a book. I told them I hadn't yet, but I wanted to someday.
Jerry then pipes up: "I think your best seller is called 'Shush.'
I think he's on to something...
