text: Ava: Billy dear! I'm such a scatterbrain. Could you please check if I've emptied the deep freeze.
  Billy: D'you mean the deep freeze in the basement?
  Ava: No. The compartment in the fridge. In the kitchen. I've put it on defrost but can't remember if I'd taken everything out.
  Billy: Just a mo.
  Billy: There's one pizza in it. Still frozen.
  Ava: Just have it. I'm sure it's in perfect condition. Thank you so much!
  Billy: Ta! A Sunday treat for me then :)) Where are you?
  Ava: At the airport. And of course out flight is delayed. By now only 20 mins :(
  Billy: Be happy that it's not cancelled.
  Ava: Still open to this development. George is already grumpy like an old woman.
  Billy: No worries. He'll perk up after the first drink on board.
  Ava: If we ever get there! "Your delay is 40 minutes". I hate it!
  Billy: Look, I have saved your fridge and my pizza. Sooner or later you'll be there. Cheer up! 
  Ava: You are right. I'd better go and have a drink with my beloved husband NOW.
  Billy: Have a short wait and a good flight!
  Ava: Ta!
target: Billy checked the deep freeze on Ava's request, and found pizza in it. Ava told him to have it. Ava and George's flight is delayed for 40 minutes and it makes them angry. Therefore, Ava and George are going to have a drink.
