Truth be told, I miss my wife, too, though I draw the line at shoe-sniffing, at least as far as you know.
Eddie Haskell sulks and sighs when my wife is away for more than an hour or so, and he seems to be smart enough to know that when she takes a small suitcase out the door that his mama will be away for a while. Eddie had the prototypical "hang dog" look as she left, and no amount of extra attention from me is going to distract him much from pining away for his mama.
