Keeping my distance

I approached the solitary man slowly. Keeping my distance, I pulled out my harmonica, showed it to him and began playing "Git Along Home, Cindy, Cindy," an upbeat folk tune often played on hammer dulcimer in the lumber camps up north.

​Doug resumed staring out the window, expressionless. I finished the tune and allowed some time to pass. 

LISTEN: Get along Home Cindy Cindy

Now what? Should I leave Doug's room at this point?
