answer: #Person1# shows Clocky, an expensive moving alarm clock, to Lily. Lily may buy one for her nephew.
documents: #Person1#: Hi, Lily. Do you want to see a cool new product?
  #Person2#: Sure, what is it?
  #Person1#: Lily, meet Clocky. It is an alarm clock and it has a loud alarm.
  #Person2#: Why does it have wheels?
  #Person1#: Because it rolls around when the alarm rings.
  #Person2#: Why does it roll when it rings?
  #Person1#: Because you have to get out of bed and chase Clocky. Then you can't go back to sleep after you turn off your alarm. I set it last night, and Clocky worked great this morning. No more sleeping late for me!
  #Person2#: Where did you get Clocky?
  #Person1#: At Tickers' Clocks in the mall. It cost about $50.
  #Person2#: It's expensive.
  #Person1#: Clocky is worth it. It can jump. Watch!
  #Person2#: Wow. Clocky really moves fast.
  #Person1#: It wants to hide. So it's looking for a place, then you have to find it.
  #Person2#: Cool. I should get one for my nephew to help him get up.
  #Person1#: Why don't you buy one for yourself?
  #Person2#: Well, my mobile phone can wake me up.
