What is she thinking!

Normal day at work.  I got home and was on the phone when the dog decided she needed to go outside.  Instead of putting her in a walking leash (I normally do) I just let her out the back door.  Low and behold she walked off the patio and onto the deck and felt that would be the best place for her to do her business.   Within 5 feet in each direction are the pine needles on the forest floor that she is suppose to go  on.  How frustrating! X(  8-}   I guess I need to lead her each and every time.   Just going to play Battlefield Bad Co 2 then read and go to bed.
