Each morning Brianna goes bouncing to class.She bounds on the playground and springs in the grass.Her gallop is more of a jump than a jog.She leaps like a rabbit. She hops like a frog.Her teachers dislike it, except at P.E.when Bouncing Brianna can spring like a flea.She's always the best at gymnastics, it's true;the pole vault, the high jump, and trampoline too.It's crazy to watch her on basketball courts,and yet there's a reason she's awesome at sports.We know why she hurdles and bounces off walls:For breakfast she always eats hard rubber balls.
