At Long Reef, two big, serious dogs cross the road to the park and wait to be released. As the woman bends to their collars, another dog appears that is small, hysterical and yellow. It leaps like a jumping bean, up and down, back feet leaving the ground and body vertical in the air. The woman fights her way to the lead and removes it, standing back, but the little dog just closes the distance and bounces, bounces, every way she turns.
