Coelho had this to say about a child. This applies to a pup as well or even better!
A child can teach an adult three things: to be happy for no reason, to always be busy with something, and to know how to demand with all his might that which he desires.Paulo Coelho
When you combine the last two points with the amount of energy at their disposal, you have a dynamite in your hands. That keeps going off again & again.
For someone who loves to enjoy the calm & quiet, read a book in peace, dwells on musing… this could spell anathema.
And an opportunity to understand oneself & what goes on within. And to deal with things not going your way. And to proverbially respond rather than react. And to learn to be in awe of this other being.
