Superman’s guardianship

"You won't even call me Dad?" Clark Kent fell silent at those words. He had been raised from childhood by the Kents on Earth. Throughout the years when his entire worldview took shape, they had taught Clark Kent to become Superman. The Kents, both ordinary Earthlings, deserved immense credit for raising Clark Kent so well. Only after his worldview had solidified did Clark Kent learn that he was not an Earthling, but a Kryptonian left behind by distant Krypton.
