A Lazy Day by the Sea

She loved seashells. She spent hours on the beach, looking for the prettiest ones. She didn't care about the sunburn or the sand in her hair. She just wanted to fill her bucket with shiny treasures. She didn't notice the time passing or the tide rising. She didn't hear the lifeguard's whistle or the screams of the other swimmers. She only realized something was wrong when she felt a sharp pain in her foot. She looked down to see a shark fin slicing through the surf trailed by her own blood.
