You had a similar situation? Someone killed himself to get away from you talking?
You are trying to claim that this absolutely absurd comedic hypothetical I have proposed would somehow have dragged up legitimate feelings about their death. Whether or not you've known someone who committed suicide is irrelevant--the dead person is not around to hear the joke. For you to get offended on behalf of all suicides on the grounds that I made a joke that is completely ridiculous in nature is fucking stupid.
