" Dogs sneak up on you like that, burying parts of themselves deep within you, bits that are only revealed later, once they are long gone. In full daylight, when you are doing something quite ordinary, one of these parts will be dug up again, quite by accident, and it will stop you in your tracks. Sometimes the memories will appear at night, in the dark, when they’re harder to get away from and it feels as if you might be smothered by the sadness of it all. "
