Read the following excerpt from a play:
High school gym decorated for a dance, characters milling aroujd the dance floor; DEV enters stage left dressed in a powder-blue ruffled tuxedo. MEGAN (with horror) Dev! I thought you were kidding me when you said you would wear that! DEV (backs away slowly, hanging his head) what was I thinking?! DEV runs off stage
How does the author most clearly convey the sense that dev feels embarrassed?
