text: Lena: Sweetie, I'm running late, gotta go!
  Fiona: Wait a sec, need to ask you a favour... When you see Mike please pretend you don't know anything.
  Lena: I'll try, but after what you told me it will be a bit difficult.
  Fiona: I'll handle it myself!
  Lena: OK, OK I won't say a thing!
target: Lena is in a hurry. Fiona told Lena about some issue and asks her to pretend to Mike as if she doesn't know anything. Lena promises she will do that. Fiona is convinced she will handle it herself.
