The way I can tell my puppy Max is falling asleep because he get's really limber and loose. His legs get floppy and looses resistance just like a baby's does before it conks off to the land of Nod.
The virtual cascade and cocoon of the summer concert of crickets and frogs.
Listening to said concert lying down on the concrete patio outside.
Watching the bluest blue of skies at night.
The way said puppy snuggles into me like I'm the only one in the universe he loves and needs in that very moment. He makes me feel wanted.
Firefly reruns on TV all day long.
Funny movies in full movie theaters.
Not stressing out about deadlines...because it's just not really that big of a deal. It will get done.
