People always say, "rest in peace" but why the hell can't we just live in peace?? Hell, doing so would make saying"rest in peace" completely unnecessary.
Especially if you are laid into a metal coffin six feet in the ground!
I would rather have an interesting life than a peaceful one.
Living in peace would indeed be wonderful. But the phrase "RIP" is just one of those "comfort phrases" we say to offer sympathy or empathy or simply a polite way of saying goodbye to someone who had died. Death is still one of those situations which makes people uncomfortable.
I like the phase used by the Black Lives Matter movement, " Rest In Power". But then again, that phrase is only used for those who are martyred.
