Sometimes poems say it best~~~
Thorns may hurt you, men desert you, sunlight turn to fog;
but you're never friendless ever, if you have a dog.
Douglas Mallock, author
and another one I really like:
I talk to him when I'm lonesome like;
And I'm sure he understands.
When he looks at me so attentively,
And gently licks my hands;
Then he rubs his nose on my tailored clothes,
But I never say naught thereat.
For the good Lord knows I can buy more clothes,
But never a friend like that.
W. Dayton Wedgefarth, author
