text: Greg: Hi, honey. I need to stay after hours :-(
  Betsy: Again?
  Greg: I'm sorry!
  Betsy: What about Johnny?
  Greg: Well, could you pick him up? 
  Betsy: What if I can't?
  Greg: Betsy?
  Betsy: What if I can't?
  Greg: Can't you, really?
  Betsy: I can't. Today I need to work long hours as well. Tuesdays are your days in the kindergarten.
  Greg: Talk to you later. I'll see what I can do.
  Betsy: You'd better think of something.
  Greg: Oh. Just stop it now.
target: Greg and Betsy have a lot of work today, so they cannot pick up Johnny from the kindergarten. However, it's Greg's turn to do it. Greg will try to find a solution.
