@ninapaley Ah, so sadly no space for out-ruthlessnessing him.
There is the "in the end, they will all die alone and will be nothing but dust scattered in the wind", but that packs less of a punch when the discussion goes that way around.
Although... now that I think of it.
There's always the "oh, how very sad you feel that way about yourself". You know, channeling the passive-aggressive, covertly superior, middle-aged woman.
I mean, it probably won't make him stop, but it might be a fun card to pull.
