Perception

A few days ago Cassidy was eating a food bar and put the wrapper on the table. Her brother walked by and it fell to the ground with his passing by the table. A bit later I walked by and said Cassidy why is that wrapper on the floor, you know better than that... What is our house rule about get it out, you put it back... she said I didn't put it there Kyle did. I had to explain to her that the wrapper was still her responsibility even though Kyle's air as he walked by her knocked it down. Had I not seen all of this, her perception would have been that she was not responsible for it anymore since Kyle knocked it down.
