I have a split reaction to this. On the one hand, lots and lots of giggles because people falling in low gravity are funny. On the other hand, sheer terror that something will go horribly wrong because they are on the moon. Granted, I know nothing did go wrong, so that frees me up to not worry about them and just giggle.
But for story fodder… looking for a NaNoWriMo plot point? Have someone fall down in a way that starts funny and goes horribly wrong.
I’m afraid Douglas Adams already used that story fodder.
You say that as if only one person is allowed to use a story seed or as if the second person would tell the same story with it. This idea confuses me.
