i think davey painted himself into a corner on this one.
i dont think he ment it like that but his shovel kept digging deeper and deeper in to the hole till he couldnt see land anymore and ditched out.
to be honest i have always thought the coffee house to be very classy and where the least of the aurgumental things happen,although theres been occations where you bicker between yourself,which is normal,your like family,family does that.
but nothing like upstairs.although im sure someone from upstairs will problably not see it that way and disagree with me.
