What a peeve!
My Mother passed recently at 98, I'm the Executor and sole heir. The peeve is vultures!!!
Some family, lots of "friends" & acquaintances, people I don't even know and it's: (take your pick):
1) I was promised this or that. (Not true)
2) I remember she (my Mom) had this...may I have it?
3) I was telling 'John Doe' about something she had & he wants it!
4) What are you going to do with (x,y,z)?
On & on about everything she had, now mine.
I've never thought of saying that to anyone who passed or their relative(s). To me that's really deplorable.

Who does that?!?!?
