Hi Barbara,
I'm not sure who in the world of LnC would find knowing Superman's secret to be fun, but other that than I could also see this working as an LnC fic.
Enjoy being able to surprise your kids; my son hates surprises of any sort. I guess your situation could be said to be one of enjoying secrets by proxy. But your point is taken; even adults can have some fun secrets.
Joy,
Lynn
