I sometimes fantasize about faking my own death.
What are you hoping to accomplish by faking your death?
I'm tired of being bothered by people.
Faking your death is just avoidance of life and it is incorrect. Learn to live and work with other people rather than trying to get away from them.
It's only a joke, calm down.
I'll take you at your word that it's just a joke, but please think about what I said. Faking your own death isn't a good way to deal with your problems, and it may just cause more difficulties for you in the long run. If you get caught faking your death, you could even get in legal trouble.
