This old man is getting his exercise by walking to the bread story for donuts and company. The butterfly represents being free.
He's looking for the dollar he dropped.
He looks like the body of the butterfly.He struggles because he sprouted his angel wings. The antenna helps him hear better. It's a metamorphosis.
He is thinking that no one notices him or that he doesn't want to be noticed. He is going to meet three old friends at McDonald's. He thinks about how the neighborhood is changing because there is graffiti on the wall.
He is bringing the butterfly to a girlfriend. He's doing what he usually does. He will do it again tomorrow. But it might be a different girlfriend.
He has a part time job.
He might be escaping from the home. Or he doesn't remember. He's lost.
He wishes that he could fly and wouldn't need a cane. He has full mental faculties and wonders who this old man is.
