Short work weeks have a way of fooling you. Especially around here. First gut reaction is, "Yay! We are off Monday! Woot! We only have to work four days." And then Monday slips past and you are faced with the grim reality that you actually still have to do five days worth of work, you now just have one less day to do it in. And then your reaction is, "Oh my God, how in the hell am I supposed to get all of this done!!! There aren't enough hours in the day!!"
So here again we see the grim truth of life, there can be no light without darkness, and no holidays with out stressed out days of playing catch up.
