take a look at this
I think the toilet seat portrait gives you a BIG clue as to the perpertrator - and believe me this is NOT all of the damage either.
It's taken me two days to find the Red Permanent Marker that created this artwork and roughly two days for the perp and the rest of his family to clean it up. Thank goodness for Magic Erasers is all I can say!
I have been very busy not cleaning - creating my own kind of art - just haven't gotten around to taking pic's and posting. The day will come.
