answer: #Person2# keeps bowling spares but no strike and #Person1# thinks it's because #Person2# is too nervous.
documents: #Person1#: You keep bowling spares but no strike.
  #Person2#: I don't know why, but I think there's something wrong with my hands. I couldn't seem to be able to control it on the first ball.
  #Person1#: I don't think it was the problem with your hands, you did several excellent spares. You have no problem with your hands.
  #Person2#: Then why couldn't I get strike on the first ball?
  #Person1#: The problem is you are too nervous. You want to have a strike so much, so you deliver the ball too hard. And when it comes to the I second roll, there's no pressure. That's why I could bowl all those spares.
  #Person2#: Really? I will try again.
