As the girl rubbed her eyes in a futile attempt to stop up the tears, she began to notice oddities about herself. For example, her right eye-socket was hollow and scarred over. Several fingers from both of her hands were missing, though the injuries didn't seem recent. Enamored with her hands, she forgot her tears, content to feel every ridge and undulation.
Soon enough, a firm SMACK sounded to her right, and she swiveled her head around to inspect. A man was floating on top of the water - wait, no. He made no effort. He was resting. Past him, a woman was pushing her hand into the water, and the water pushes back. When the other woman looked up, the girl made eye contact with her. Almost instantly she understood. The water was different. Curiosity overcame her fear, and, wishing to find out for herself, she extended a leg over the box and pushed her toes into the water. It held, but dipped down around her foot. Delighted, she put her other leg down and stood on the water. She wobbled - though it held her, it was trampoline-like, providing little stability. However, she was practically giddy with this discovery, and a strange barking cough emerge from her throat. It was uncalled for, and she frowned, unsure of what it was. It was as if her mind was a vat of dismembered thoughts, swirling at incredible speeds. She snagged one. Laughter! It was laughter. She laughed again, impressed with herself.
Turning her attention to the man resting on the water with a smile, she took a step. He waved his hand to her and she took another step, and another, and another, until she was a foot or so from him, peering down at his prone form. The water showed no sign of breaking, but when he made a sound - slow, almost painful - she attempted to step closer, and the water gave way. The two plummeted through the sudden hole in the water to the colder, wetter underside. This is how she remembered water.
Luck was working both for and against the pair. The water was crystal clear, and shallow - possibly ten feet deep or less. A small reef rested just below their feet. However, the girl was too distracted by the water that rammed its way up her nose and in her mouth. She choked, and flailed in a blind panic. The water, though less tense, was almost jelly-like - the more she tried to move, the harder it became. Her panic increased. When she attempted to propel herself upward, she was met with equal downward force. A leftover sob from her earlier cry forced its way out and she sucked in a mouthful of water. Her throat burned and she shut her eyes to all the bubbles she stirred up. Not even five minutes out of the coffin and she's going to drown - what a pity.
