Raven Lunatic

"It's a blackbird, not a raven," she cried.
"But it's acting more like a raven," I replied.
"Doing raven stuff, like walking about with
that 'air' of something sinister," I added. 
When the bird jumps off the fencepost,
walks over to you and starts to say
something, but doesn't find the words....
No, no, no...wait....who is the lunatic here.
