Carol, this is a funny and heartwarming vignette. I liked Lois's idea that Martha might have some embarrassing pictures of Superman (although what they might be she, of course, has no idea). And where did you get the idea for the name of the beer? That was funny! "Drink Kansas Tornado! One too many and the room spins and you're in Oz!" And the ending was sweet and tender, promising much while revealing little.
If you choose not to write a sequel or a continuation because you've said all you intended to say, that's fine. But don't think you've lost your touch or that your muse has gone on permanent hiatus, because neither of those things has happened. Good story. Thanks for sharing.
