The Perpetual Rotating Cadet

Frankie and Bridget are working in the VT library when they spot some ROTC cadets walking on the sidewalk outside their window.  They observe that while walking to class in their uniforms the cadets have to walk in stiff, straight lines parallel to the sidewalks and turn at right angles on the corners, and are only allowed to turn to the right.  One of the cadets gets “stuck” somehow at an odd spot on the walkway and is locked into a perpetual loop of taking two steps and turning right.  Frankie and Bridgette stare out the window at the poor cadet.

“Are we allowed to, like, help him or something?”
“I dunno.  What should we do?”
“I think he’s supposed to figure this out on his own.”
“It’s like a gif.”
“Yeah.  It is like a gif.”
