Don’t want to ruin the elastic with chlorine.” He gave her a wide smile and a salute, and (taking a brief moment to check he wasn’t at the shallow end of the pool and about to break his neck) executed a somersault into the water, coming up a moment later pushing his hair back and shaking the water out.
