Nam: Dad, the printer isn’t working.
Mr.Nhat: It is new. There shouldn’t be anything wrong with it. Have you turned it on yet?
Nam: Yes, I have already done it.
Mr.Nhat: Have you connected it properly?
Nam: Oh, Dad. I know how to connect a printer.
Mr.Nhat: Has the plug come out of the socket?
Nam: No, it’s OK.
Mr Nhat: I have no idea what the problem is. This manual isn’t very helpful.
