Its like hair... (Mom)

The dog was laying down and I was walking past, there was a chunk of hair ready to fall off the dog, so I leaned down and I pulled it off, and there was some more so I pulled it.
My mom is behind me and yells at me, "QUIT PULLING THE DOG'S FUR, IT HURT JUST LIKE IF YOU WERE PULLING HAIR!!"
I Turned and looked at her, "mom, fur is hair"
