  Martha: hey, sorry, I have a dentist appointment.
  Jack: really? again? I think you're avoiding me...
  Martha: calm down... it's not my fault I care about my teeth
  Jack: but it's so strange that everytime I want to hang out with you, oddly enough you're busy
  Martha: trust me... it's a coincidence :)
  Jack: so what now?
  Martha: Let me think
target: Jack wants to hang out with Martha tomorrow, but she has a dentist appointment. He suspects she might be avoiding him.
