My folks' dog, Mick, is a good dog, the third in a series of labrador retrievers over the last 40 years (yes, they've each lived to ripe old ages). But Mick, unlike the previous two, has had just my folks in the house most of the time. And even though he is a lab, arguably one of the friendliest breeds around, I think he needs a break sometimes from the chaotic presence of two five-year-olds.
Of course it could just be he's enjoying the view.
Or maybe he's posing, waiting to be admired.
