Plays it cool

Mr. Branson though embarrassed tried to play it cool. He was comfortable with his body, he’d just prefer not to show it off. But, with this predicament he had no choice, instead of running to hide, he tried to play it cool.

He removed his tank top and said, “Why did you guys stop stretching? Are you intimidated or something?” The guys in his gym class ceased their laughter, and became upset once again.

Mr. Branson continued class as usual. They swam some laps; They learned a new stroke, and started a game.

Did something happen during the game?
