This is the rationale behind every protagonist is really a vampire! story ever written.

Oh. Even Agyar? Because I thought that worked out really well.

I am also a fan of not having your characters spill their guts every which way. Dribble the information out while the reader's looking the other way! More fun that way. (Of course, I have recently been reading a whole string of "cozy" village murder mysteries whose narrators have dire lay-bare-your-heart tendencies.)
