Visiting Uncle Franks grave

Aunt Ginny asked us to give her a hand cleaning up Uncle Franks grave site the other day.  She can't get down to pull the weeds, so we all went together to give her a hand.  While Ed and I were digging out the weeds and the crabgrass.  Michael asked why are we digging up Uncle Frank.  Aunt Ginny seemed to get a kick out of that.  He also asked her what the head stone said.  She read it off to him and at the end she was telling him that they left a spot and will have to put the date she dies on it.  He looked at her very sincerely and asked when that will be?
