So, after a little toying with the story, I came up with one. Which is why Sean and Liz (everyone give a nice hello to the story's main characters) do have some sort of reason for up and leaving, even though they're apparently intelligent, mature, simpatico teenagers from secure home. Now, the only question left is why? Why did they do it?
UPDATE: All files in HTML now! Wa-hoo! Chapter Four is only half written, and Ch. 3 may get some changes to it, but...this tale is actually drawing to a close. Soon. *g*
