Nope. I never delete them !
I didnt delete them...just keep them in my friends list
maybe keep them.. but never wish that that they message me.. that's quite scary ugh..
I still get add a friend invites from people who died before i had a face book account!!! It's creepy, and saddening.
I'd delete cause their dead, its not like their going to contribute from beyond the grave. I'm not even on fb, but thought I'd just say.
