I can’t understand it.  I thought they would be pleased that the filter was shredded. Still, I had better sucess today.  They left the kitchen gate open.... I managed to find 2 sausage rolls, a packet of blueberries, the recycling, another water pistol and a roll of silver foil (I prefered the cardboard to the foil itsself.). Then I went into the lounge and removed a pencil and the calculator from the coffee table.  I heard later that the calculator is still working, but I sure put some lovely teeth marks in it.
