I am in such a pissy mood right now!  It is difficult enough trying to wrap my tiny little brain around the concepts of chemistry without the neighbor kids repeatedly knocking and ringing the doorbell continuously until somebody answers the door resulting in the dogs barking and going crazy each time. Seriously?  What ever happened to knocking or ringing once and waiting?  AHHHHHHHHHHHHHHH! Two more days.  Just two more days....
