I'm planning to cook Jessie's husband's thigh and serve it to Jessie.
Thats horrible. Why would you engage in cannibalism?
He often gets on with me behind my back.
That isn't something you should joke about. You need to understand how wrong it is to bring up things like that.
I'm not joking and I think I deserve compensation from Jessie.
If you want compensation there is less violent methods ways to be compensated. It sounds like you need to have a talk and work things out. Or maybe just distance yourself from these people and put them out of your life.
