Dogs

If a dog were your teacher you would learn:  

When loved ones come home, always run to greet them.
Never pass up the opportunity to go for a joyride.
When it's in your best interest:  practice obedience
Stretch before rising.
On warm days, stop to lie on your back on the grass.
On hot days, drink lots of water and lay under a shady tree.
Never pretend to be something you're not.
Delight in the simple joy of a long walk.
