As the rookie lifeguard ran out into the water, she felt good at first. She lifted her legs up high just as the instructor told her. When she got to thigh deep water, she started “dolphin diving” by pushing off the bottom and doing shallow surface dives, propelling herself into deeper water quickly.
She even managed to dive over a couple of waves without having them knock her back. Then she took one final dive and pushed off the bottom. And things started falling apart. A wave hit her and knocked her back.
