documents: #Person1#: Hi, Mr. Adams?
  #Person2#: Ah, Yes. You must be Kelly. Thanks for coming.
  #Person1#: Here's my card.
  #Person2#: Oh, the entrepreneurial spirit. It hard to find a good babysitter on a Friday night.
  #Person1#: Well, I like watching kids, and I need the extra money.
  #Person2#: Well, I heard you were one of the best and most affordable babysitters in the area, and ...
  #Person1#: Uh, well, I'd like to talk to you about my new rate increases.
  #Person2#: Rate increases?
  #Person1#: You see, Mr. Adams. I've consulted with my financial advisor [What?]. Uh, my mother, and she says I should charge more per child since I do cook and clean your house while you're away.
  #Person2#: Oh, I see. So, what do you have in mind?
  #Person1#: Well, as I see it, I'd like to ask a dollar more per child per hour, and overtime after midnight. Based on my calculations, that's only 10.23% above the going market, and I'm now a certified babysitter with training in CPR.
  #Person2#: Oh, I never knew there were courses and certifications in babysitting.
  #Person1#: Times are changing, Mr. Adams. I have to figure in expenses for a benefits package to cover college tuition, retirement, and my stock portfolio. Well, I tell my dad what to do.
  #Person2#: Ah now, you're pulling my leg. I mean, how old are you anyway?
  #Person1#: Old enough to be a tough negotiator.
