In “Lady’s Bouvier’s Lover” episode, it seems like mr. Burns doesn’t open birthday cards (or even any kind of card?). Well, I like to imagine that Smithers sends him romantic poems and letters in his birthday but also every holiday, in hope he’ll acknowledge his feelings, although he knows that he’ll never open them and deep inside he’s happy he doesn’t read them.
What if one day Burns decides to open them and reads Smithers birthday/Christmas/whatever card? And at the beginning he’s confused but then thinks it’s a joke?? And he thanks Smithers for the funny card and praises him for his writing skills??? And Smithers feels both upset and embarrassed????
