It was a lovely day as you made your way to your local beach. You wanted some time to yourself, the weather was inviting, and the thought of bathing in the cool sea was enticing. Stepping onto the warm sand, you slowly strode down towards the water. Peeling off your shirt, you tentatively took a step into the lapping waves. You stood for a few moments, acclimating to the water’s temperature, before noticing some interesting rocks. As you examined the rocks, you felt something brush against your leg in the water.
