This is a phrase I hear often from my mother. Each time I hear it, I want to smack her. Woman, you’re alive. You do not have a grave yet, but rest assured if you keep saying it, you’ll have one sooner than expected.
Furthermore, even if you had a lot in a cemetery already picked out pending your death, why the fuck would someone be walking over it ?! Where on this goddamn planet are you buried in such a place that people walk over it ?! The pavement ?!
Logic; introduce yourself to it.
