Waiting for the postman was the highlight of her day. Marnie was a great look-out, she loved her special place sitting on the back of the sofa so she could look out of the window in order to protect her family. The postman was the trigger, any sight, smell or sound and she was off. She felt pleased with herself once she had warned him. She would low growl under her breath, muttering to herself after the incident of this unwanted visitor had gone.
