Signs.

Tonight I sent Brynn into brush her teeth and she shut the door. Bad sign.

I knocked on the door and tried the handle. It wasn't locked, so I cracked it open.

"You alright?"

{flash of quick movement}"oh yeah. Fine. brushing my teeth."

"Ok. Hustle up."

She finished and I shooed her to bed and tidied up the teeth mess she left behind. What do I find on the counter?

A set of wet vampire teeth. Oh, she was brushing her teeth alright, her vampire teeth.

Must be Halloween.
