If I see you standing on an unstable chair with a noose around your neck, I may feel an obligation to let you know that you are standing on an unstable chair and that there is a noose around your neck, but if you ignore me, or worse yet, deny that there is an unstable chair or that there is a noose, I will simply walk away and let matters take their own course. Unless you piss me off. Then I’ll kick the chair.
