Student:  "Mrs. A, why do you have your coat on?  Are you cold?"
Me:  "Nope.  I just really like my coat.  Look at it.  Isn't it cute?  It's got a nice pattern and a bunch of dog hair on it."
Student:  "Do you have a dog?"
(silence)
Me:  "Nope, I just let dogs in my neighborhood jump on me so that I can have dog hair on my coat."
