you're a fisherman who goes out in the sea every week to catch fish on your boat, you do this for a living to get by. you place the bait on the hook and cast the hook in the water.

as you wait, you feel a big tug on the line meaning something caught it. you start to pull it out of the water, it's really heavy. you manage to pull it out and it jumps on the boat, its a merman....

"you idiotic human..!" he utters harshly, he has an intimidating gaze which slightly scares you.
