Which is exactly right in theory, but you have to make *some* allowances in
practice if there are women between the ages of 12 and 60 or so in the house.

Having just installed an $18K super computer controlled septic system that would

graphic negotiations with the SO, dropping a few bucks every year or two to get
the waste tank pumped out seems a fair trade...
