I know it all

I recieved an intersting phone call today.  Seems someone wanted to get a price on a property I listed just yesterday.  Once I told her the price she became insulted and downright nasty.  Told me she was way to smart to be told what I told her.  HUH?  Oh yea she new everything.  Then why did you call me then?  Oh well I had to play nice and be glad I wasn't her agent.  Oh yea she knew that also.
