Playfulness is a natural gift that requires living in the present. No past or future imaginings can replicate the joy of the moment. All new born animals including humans are born with their playfulness intact. For many, this attribute is pushed below the surface once the age of reason is reached. Thankfully it is uncovered again with age and the waning need to live for the future.
The easiest way to reactive present living and playfulness is to surround oneself with an environment full of the sounds, images, smells and behaviors that invite its presence.
Fortuantely, I have relatives that are happy to share their retirement puppies and am posting some captured scenes to stimulate you.
Enjoy in joy.
