Oh, he's definitely been doing her. Haven't you noticed that brand new batch of rugrats they have? I can't imagine having kids that are essentially grown and in college, and then deciding to start all over with a whole new set. She's several years older than my mother and has a 5 & 3 yo.
Maybe it was their son's death that spurred it, but it still seems really late in the game for all that.
I like her, though. She's a really smart lady.
