It's a brief scene that quickly makes its dramatic point. The scene also introduces Hank's friends without explaining who they are. That they're close friends of Hanks is established because they are there with him at this moment. By limiting the number of characters on the screen, the audience is guided to focus on what the author is setting up as dramatically at stake. Third scene, a man at Hanks' office approaches and offers a card about his therapist.
Hanks pulls out a handful of cards about various recovery groups.
The scene also gives us background information about Hanks. Answer, quit his job and move to another city. Next scene, Hanks and his son are at the airport, leaving. Again note the dramatic focus of the story. It's not about whether it's right or wrong that Hanks move or not, so there are no scenes where Hanks talks about his decision.
