What you can learn while you're walkin' the dogs:
The next smell is always a new one.
Sometimes straining against the leash is a good thing.
A trail in the woods is never boring.
Anything that grows or stands upright is never boring.
You don't have to look up, necessarily, there's a lot of stuff that's really interesting no more than two feet above the ground.
Other dogs are just amazing, squirrels not so much.
More or less, it never hurts to try to pee one more time.
