When you’re really down, and don’t want to talk to anyone, and don’t want anyone around you, a dog will just lay by your side and slowly work his head into your lap. If you don’t pet him, he’ll shift or nod his head until you do (even if it’s only by his motion).
Slowly your blood pressure evens out, your breathing slows, and your mood shifts. Everything might not be right with the world, but living with a dog sure makes the world more bearable. There should be a Nobel Prize for dogs. There really should.
