Visitor

He sat alone in a coffee bar, silent, motionless, his eyes fixed on the door. He didn't move a muscle nor avert his gaze when I passed him to take a seat at the adjacent table. He didn't move when the waitress brought me and my partner the coffee. He sat in silence, like a statue, which he might as well have been if not for the breathing. Meanwhile, I was chatting about insignificant things while sipping my coffee. Somebody entered, one or two people left, but he barely moved. After a while another man entered, a box of cigarettes in his hand. He suddenly jerked up and pulled towards the man, then backed up as a leash tightened. The man came to him, sat at the table and stroke his dark hair. "Good boy! You looked after our table while I was out smoking. Now say hi to your friend over there."
The big black mutt's snout touched my hand, his tail wagging.
