Oh I get it. I really didn't get why The Great Lakes weren't called Seas. I happened to have a globe in the hallway because my parents house has more bookshelves than walls.
They really oughta be called seas, those fuckers are huuuuge. Childhood me woulda agreed with you. Maybe. We did live next to the Atlantic Ocean, but I think if the argument was "Can't see the other side" me would have accepted this as what an ocean or sea should be.
