I'm planning to chop my cat's head off and roast it over the fire.
What? Why would you do such a thing?
I need something to eat tonight.
There are plenty of other things you can eat. You should not be chopping off your pet's head.
Roasted cat meat is really yummy.
It's obviously not okay to roast and eat your cat's head. I think you shouldn't even joke about it though, or someone could report you. They'll also think you're a bad person.
