Lemon Shark

Sharks are a fear almost everyone has. We often fear those we don't understand (and that could be anyone). Fishermen swimming in warm waters cast nets for fish. Sharks often get caught in them and suffocate painfully, unfairly. One of them, a male lemon shark, his throat tied with nets, was suffocating painfully on the bottom, unable to feed. But you're not an ordinary person, are you? You'll save him, right? Taking a sharp object and cutting the nets, you free the shark. He slowly and barely breathes, scared and hungry.
But before he swam away, he glanced back at you strangely. Soon, a month later, you're back at sea. Among the fish shadows, you find the same shark, swimming purposefully toward you. The predator remembers your face and was grateful. He swims around you now, not hunting, but simply not knowing how to thank you.
