Took this shot when I was in Barcelona. There is something so poignant about this scene. The master is probably homeless or a traveler who missed his train ride for the day or perhaps a wandering street performer who sleeps along the alleys at night. Whoever he was, he probably had all his stuff with him in his travelling bag. That... and his loyal companion.
And his companion, as if oblivious to the status of his master does not care. Sleeping snugly with him, he is at home. And that's what all the matters.
