WTF is up with my dentist?

I had a little appointment last night.  Nothing much, just a cleaning.  First she digs around in my mouth for like 20 minutes with a sharp jagged piece of stainless steel and then has the balls to tell me that my gums are bleeding.   Well no shit sherlock.  Then she precedes to have a conversation with me while she's wrist deep in my mouth.

Her - "How are you today"
Me - "Ughh ohh?"
Her - " I'm fine thanks.. What are you doing for thanksgiving?"
Me - "Ugghhhh"

Seriously wtf is up with her?  Does she like having these one person conversations with people who can't possibly talk back?  Must be nice.
