GRGHHL stares out, over the vast expanse of the ocean. In the distance he sees a ship, slowly beginning to descend behind the waves. He sees first the hull disappears, then the masts, ...then the ship is gone. GRGHHL contemplates this phenomenon, having no concept of such things as curvature, or Earth, or truly much of anything. As he mulls this over, a bird swoops down, and scoops a fish out of the water. He flies away, wiping all thoughts of the boat from GRGHHL's mind. Having accomplished his daily beach visit, GRGHHL turns away, and heads back to town.
Thank you. I enjoyed my time with GRGHHL. I admit I cheated for the password puzzle...
