text: Gwen: Great job, Joe, you only had one job - water the plants.
  Joe: I did.
  Gwen: I don't think so. I just got back home and they look pretty dead to me.
  Joe: They were absolutely fine yesterday. I watered them just like you told me.
  Gwen: It's a desert, Joe.
  Joe: What am I supposed to tell you, Mum? Maybe there was something wrong with the water.
  Gwen: Which watering can have you used?
  Joe: Green one.
  Gwen: Aha, thanks Joe. We don't have a green watering can.
target: Joe didn't water the plants and killed them.
