answer: #Person2#'s left-handed and works slowly. #Person1# tells #Person2# #Person1#'s also left-handed and asks #Person2# to get suited to the work in advance instead of complaining about the machines.
documents: #Person1#: Hey, you. Can't you be a bit faster? You make the whole group wait for you.
  #Person2#: How can you blame it on me? I'm having trouble in operating this kind of machine. It is designed for you right handers.
  #Person1#: You always complain about these machines. But you are not the only one using your left hand.
  #Person2#: Really? I don't know any others who are the same as me.
  #Person1#: To tell you the truth, I'm also left-handed.
  #Person2#: You?
  #Person1#: Yeah. You should spend some time getting suited to it in advance. Then you can do it quickly.
  #Person2#: Is that what you have done?
  #Person1#: Yes. In fact, it pays to use both hands.
  #Person2#: OK, I will try.
