The dog-walker receives his response and nods his appreciation to her. He’s handsome, in a weathered way. She marks the message for later consideration. It would not be inappropriate to ask him out for a drink, if he’s single. A conscientious fellow with good shoulders and a well-trained dog. So far, so compatible. She tells the machine to run a background check to be sure he’s not a plant. After a moment of hesitation, she instructs it to sequester the results. If he is not actually dangerous, she chooses not to pry. It hinders conversation, later, if she already knows everything about her date.
