Making Coffee

I was making a pot of coffee after dinner and placed the pot on the heating plate crooked.  I put a cup of coffee from the previous pot in the microwave to heat it up for Barb and left the room.  When I got back to take the coffee out of the microwave I noticed something was wrong with the coffee maker.  There was no coffee in the pot yet.  I noticed the pot was crooked and jiggled it around and into place. Suddenly a whole bunch of coffee came swishing out because there is a valve in the filter that doesn't open unless the coffee pot is placed under it.  If I hadn't come back to get the cup out of the microwave, there could have been a big mess in the kitchen.
