Have you seen this? This poor man is walking his dog and approaches the steps to his own home. He looks scared to go up and so ends up going out into the park with the dog. He can't go home! He doesn't directly mention it, but certainly suggests it with his "I used to be afraid of doing some things..." while looking at the steps to his home.
After Advair, he goes up the steps, gets his son--this man couldn't get to his son without Advair; he lived on the street, walking his dog to avoid looking too homeless--and plays frisbee in the park.
It's so sad.
