Well, Mitsuru's mother is... VERY high class. She's one of those stereotypical rich women :D;;; While, oddly enough, neither his father, nor his grandmother (who lives with him) is.. o.o;;

Actually, the line "I envied him his youth" is from Shadow of Memories. Doctor Wagner says it to Homunculus when he wishes for eternal youth (the silly fool)... :3; that's where I got it. It might be from some Shakespeare thing, though XD;
