Most Helpful Girl
As a writer myself, I would be attracted to this person. If their head phones are plugged in, it's harder to talk to said person. I would also be more hesitant to talk to them if they were sitting in a place that had no other seats or looked difficult to get to, or cramped. If this person looks very focused on their task, I wouldn't come up. If, however, this person is constantly looking up and smiling at people, I would find them friendly and approachable, and probably ask what they're reading or working on.
