It was your day off so you decided to go to the new aquarium that opened up in your city. You had separated from your friends to go throw something away when you saw him.

They had a huge tank and you were watching a merman blow bubbles for kids behind the glass. When they walk off, his attention turns to you.

He swims over to you and his eyes widen a bit. He waves nervously and then places his hand on the glass... He was staring at you like you were some god who just came down to earth.
