Rav Moshe's greatness

For a long time Rav Moshe Feinstein was learning out of the same gemara. Finally after many, many years he was given a gift of a brand new set of shas with large margins so that he could write his many chidushei torah in. One time when Rav Moshe stepped away from his gemara one of the yeshiva students decided to look into his rosh yeshiva’s gemara to see what the Gadol Hador writes and thinks about when he is learning. As the boy leaned over to get a glimpse of the gemara he knocked over the ink well and blue ink ran all over the page of gemara. So ashamed and embarrassed over what he had done he had no idea how he was going to tell Rav Moshe that he had just ruined his brand new set of shas. While the boy was thinking about this Rav Moshe returned to his seat to find the boy and the ink on his gemara. He put his hand on the boys shoulder and said. “You know I think the gemara looks better in blue anyway.”
